Ok.. currently I have a 2.33ghz C2D 17" Macbook Pro I am selling it because it is to big for the portability I need. With the funds I want to get an iPhone and Asus Eee PC this leaves £700 for a new desktop. The desktop needs to be as powerful as the Macbook Pro. Which one should I get for £700? I will be able to claim the VAT back and get Edu discount if this helps.
