To me, computer rankings should be discriminated against by their originality, ease of use, and so forth. IMHO, computers which run Windows are all the same. There's nothing special about a Sony Vaio versus an HP versus a Dell -- commercially they run the same OS, so other than package deals, there is nothing to set them apart.
Criteria should include ground-breaking technology, not the same rehashed crap over again. The various Ataris, Apples, Commodores, Amigas, Sinclairs, and so forth... these computers brought forth various revolutions.
