What is Yoper?

The best OS you have ever tried.

Yoper is a high performance operating system which has been carefully optimised for PC's with either 686 or higher processor types. The binaries that come with Yoper have been built from scratch using the original sources combined with the best features of from the major distros. However, Yoper is not like the general purpose distros such as Redhat or Mandrake. It is high performance. It is compact. In fact Yoper is one of the most standardised linux's that you will find and hardware performance is better than that of any other commercial OS. With Yoper it is possible to import packages from all the other major distros including rpm's, deb's, and tgz packages.

Developed by AndreasGirardet from New Zealand.

Cut the hype. It's just another distro, and by no means the best there is. A number of the above claims are dubious at best.

This was where my real problems with Yoper began. Without getting into all the details (this is a comparison, not a complaint summary), it quickly became apparent that Yoper was only in the game for Yopers benefit. They did manage to build an impressive distribution (RC4 being the exception), but their support left a lot to be desired. They've deleted their knowledge base and message forums no less than 3 times in the last couple of months, and when I did run into a problem, they refused to respond or answer my questions (and with the message forums deleted, I didn't have the option of turning to that as a resource). Similar complaints began to pop up on both their forums, and on other sites, to which the company responded with insults and diatribe, referring to anyone who voiced an opinion as a "Slashdotter" and refusing to acknowledge anyone's issues.

Perhaps this situation has changed, but just recently they posted a long message on their site claiming that anyone who complained about the quality and/or treatment we received was simply a Slashdotter (among other things), and that they didn't want to service us "geeks". Instead they claimed that they were very successful in the New Zealand market, and that they didn't need or want users like us.

Easy enough... I deleted the Yoper releases, pocketed the money I'd set aside to purchase Yoper with, and moved on.
