Possible XP > Windows 7 Upgrade

[Technical Ben]

Sadly not what the general public, and computer manufactures and review sites think. Its been the biggest flop since Vista.

Kind of true. The OS is probably the best. The GUI... yeah, I should not get involved in the discussion. 
It's almost the opposite of Vista really. Vista had a nice/nicer/similar GUI to XP and was an "upgrade" in that department IMO. But under the hood, while "upgraded" in theory, it muddled and crashed along.
