"I've heard WinXP removed the cmd/command prompt."
No, Microsoft didn't remove the CMD.EXE or COMMAND.COM prompt from Windows XP. But Windows XP has reduced functionality, in many ways, not just in the command line. The command line is a big embarrassment because of its limited capabilities, but at least in Win 95 it worked. With every version since then it has worked less well. (There are two kinds of command prompt, and, according to Microsoft employees, the differences between them are not documented.)
The command line prompt sometimes begins to display short file names. Microsoft employees say that Microsoft has no fix, although someone not connected with Microsoft did make a work-around.
Cutting and pasting into a command line program often puts successive extra spaces before each line. Microsoft employees say that there is no plan to fix this.
The fast paste mode that is in Windows 98 is gone in Windows XP. Microsoft employees say there is no plan to fix this.
When using the command line interface, Windows XP doesn't always update the time. After several hours, the time reported to command line programs can be several hours in error.
There is a DOS program called START.EXE that can be used to start other programs. But it does operate the same way as in other versions of Windows. It starts a program, but cannot be made to return control to the command line program as previous versions did. There is no technical reason for this; it is just one of the shortcomings that are allowed to exist.
People often say that DOS has gone away. But Microsoft still calls the command line interface DOS, and in Windows XP Microsoft has added new programs for configuring the OS that work only under DOS.
Sometimes when you press a key while using Windows XP, it is seconds until there is any response. Apparently there is something wrong with the CPU scheduler in XP, because there are a lot of complaints about this in the forums and MS people have said that they are working on it. On one particular fresh installation of XP, on an Intel motherboard with either a Matrox G550 or an ATI Radeon video adapter, it requires 18 seconds to display a directory listing of 94 items. This is apparently related to a bug in the video software, not the adapter drivers.
Something is wrong with the Alt-Tab display of running programs under Windows XP. If there are a lot of programs, not all of them are displayed. The order jumps around in a seemingly random way.
Although articles often say negative things about Microsoft, I've never seen an article that fully documents how bad the situation really is. Microsoft's management is so bad that the company has become self-destructive. For example, Windows XP is spyware. Here is a list of ways Windows XP connects to Microsoft's servers:
These are just the ones I know. There may be others.
So, if you use Windows XP, your computer is dependent on Microsoft computers. That's bad, not only because you lose control over your possession, but because Microsoft produces buggy software and doesn't patch bugs quickly. For example, as of July 7, 2002, there are 
18 unpatched security holes in Microsoft Internet Explorer. This is a terrible record for a company that has $40 billion in the bank. Obviously, with that kind of money, Microsoft could fix the bugs if it wanted to fix them. Since the bugs are very public and Microsoft has the money, it seems reasonable to suppose that top management at Microsoft has deliberately decided that the bugs should remain, at least for now.
It seems possible that there is a connection between all the bugs and the U.S. government's friendly treatment of Microsoft's law-breaking. The U.S. government's CIA and FBI and NSA departments spy on the entire world, and unpatched vulnerabilities in Microsoft software help spies.
Windows XP, and all current Windows operating systems, have a file called the registry in which configuration information is written. If this one (large, often fragmented) file becomes corrupted, the only way of recovering may be to re-format the hard drive, re-install the operating system, and then re-install and re-configure all the applications. The registry file is a single, very vulnerable, point of failure. Microsoft apparently designed it this way to provide copy protection. Since most entries in the registry are poorly documented or not documented, the registry effectively prevents control by the user.
Note that Microsoft does not support making functional complete backups under Windows XP. Look at Microsoft's policy about this: Q314828 Microsoft Policy on Disk Duplication of Windows XP Installation. Only those who work with Microsoft software will understand the true meaning of Microsoft's policy. Since almost all programs use the registry operating system file, if you cannot make a functional copy of the operating system you cannot make a functional copy of all your application installations and configurations. There are other software companies that try to fix this, but they don't work well, and Microsoft can, of course, break their implementations, as they have often done with other kinds of competitors.
Because the configuration information for the motherboard and the configuration information for the are mixed together in the registry file, the registry tends to prevent you from moving a hard drive to a computer with a different motherboard. That's another implication of the above Microsoft policy. So, if you have a motherboard failure, and a good complete backup, you may not be able to recover unless you have a spare computer with the same motherboard.
Note that Windows XP Professional can support only ten simultaneous incoming network connections. If you want more than that, you must use Windows 2000 server, and pay much, much more. (There is no Windows XP server yet.) Many businesses have very light network traffic; they just move files from staff member to staff member; they really don't need a dedicated server computer. The staff computers could easily handle the load except for this artificial limitation.
Apparently because the Windows XP GUI comes from Windows 98, Windows XP has the same problem with desktop icons that Windows 98 has. The icons sometimes flicker. Sometimes they move themselves around, particularly after the user switches monitor resolutions. Also, sometimes the taskbar settings un-configure themselves, as they do in Windows 98.
Only technically knowledgeable people know how to avoid signing up for a Microsoft Passport account during initial use of Windows XP. The name Passport gives an indication of Microsoft's thinking. A passport is a document issued by a sovereign nation. Without it, the nation's citizens cannot travel, and, if they leave, won't be allowed back in their own country. In Microsoft's corporate thinking, the company seems to be moving in the direction of believing that they own the user's computer. Most people are both honest and intimidated. Apparently about 95% do whatever they are asked on the screen. They give their personal information to Microsoft. They don't realize that, if they feel forced to get a Passport account, they should enter almost completely fictitious information, since the real question is not "What is your name and address", but "Can we invade your privacy". The honest answer to this is "No, you cannot invade my privacy", and the only effective way to communicate that is to give completely fictitious information. Since it is the educated people who have computers, Microsoft is building a database of the personal lives of educated people. Microsoft knows when they connect and from what IP address (which tends to show the area), what kind of help they ask, and information about what they are doing with their computers, including what music they like. It is not known, and there is no way to know, how much Microsoft or other organizations make use of this information, or their plans for future use.
Not only has Windows XP definitely gone further in the direction of allowing the user less control over his or her own machine, but with Palladium, Microsoft apparently intends to finish the job: Microsoft will have ultimate control over the user's computer and therefore all his or her data. Even now, under Windows XP, a recent security patch requires that the user agree to a contract that gives Microsoft administrator privileges over the user's computer. The contract says that if a user wants to patch his or her system against a bug which would allow an attack over the Internet, he or she must give Microsoft legal control over the computer. See this article also: Microsoft's Digital Rights Management-- A Little Deeper. You may need to be a lawyer to take apart the crucial sentence. "These security related updates may disable your ability to copy and/or play Secure Content and (my emphasis) use other software on your computer" legally includes this meaning: "These updates may disable your ability to use other software on your computer." Note that the term "security related updates" is meaningless to the user because the updates have no relation to user security. So, the sentence effectively means that Microsoft can control the user's computer without notice and whenever it wants. That kind of sentence is known in psychology as "testing the limits". If there is no strong public complaint about this, expect to see more and stronger language like this.
This Register article shows the direction Microsoft is going: MS Palladium protects IT vendors, not you. Absolute power corrupts absolutely, and Microsoft is well down that road. See this ZDNet article, also: MS: Why we can't trust your 'trustworthy' OS.
Microsoft's self-destructiveness does not mean that the user should be self-destructive. There is no need to apologize for using Microsoft software. The correct solution to abuse is persuading the abuser to stop being abusive. Once I posted to a Slashdot story a link to an article on a web site of mine. By far the majority of visitors from the Slashdot story used Microsoft operating systems. Rather than feel embarrassed because Microsoft is abusive, action needs to be taken to prevent the abuse. If you are against Microsoft abuse, you are not against Microsoft; you are more pro-Microsoft than Bill Gates.
These Microsoft policies mean that any government which wants to be independent of the United States government, and any government which represents itself as controlled by the people, cannot use Microsoft operating systems, or other Microsoft proprietary systems.
