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.
