Hewlett Packard. A computer company. They have existed for some time, and they still exist.
They don't exactly have a reputation for quality. -- Lies.
HP have bought Compaq, so many more corporate computers will be branded HP.
HewlettPackard are actually not a bad computer from the corporate sense, in fact their business PCs are quite neat. their backup service (as was compaq) is extremely good, cant really comment on home PCs, but i have known many people having issues. however HomeUsers? normally equal NumbNuts?.
