Am I jealous? Not really. Its a very good price for the system but its got Vista on it which I wouldn't want, it has quad core which at the moment you don't really need (though I admit it will be handy for future programs that are written to take advantage of it) and lastly it has a very poor graphics card and has a low spec power supply meaning that if you did decide to fit a decent graphics card you would have to buy a new power supply as well.
Don't get me wrong. I am not slagging the computer, for most things it should be very fast indeed and thats a good price especially considering it comes with 3 gig of RAM all for less than £400. Its a good deal at that price.
