Again power over 1) reliabilty 2) looks 3) quality
And most of all each user has there own needs some just want a pc to use dial up for hotmail and to write documents.
Others want hardcore high res Anti Alias gaming with super graphics and mega fast Broadband connections.
All ends up what you want...for most users I find I-Mac's are a better choice for the average user, and when I went pc world recently at Oldham i was speaking to someone who actually was interested in what I wanted..who recommend a E-Mac £499 and I have tested one there and am now seriously thinkin of getting one for online work and keeping the windows one for offline stuff such as messin with the primitive thing which is windows lol..
But each to there own
