I am planning on buying an iMac towards the end of the summer before the new school year. I want a 24" iMac but I want: Upgraded Processor (2.33) Upgraded Memory (2g) Upgraded Vid Card (256mb 7600GT) Wireless Keyboard & Mouse I want to buy it off of apple.ca so that I can upgrade it and so that I can get the educational discount, but I am worried about returning it. Thats where it's better if I buy from Futureshop or a store where I can return it (but then I don't get an educational discount or the option to upgrade from a retailer) If I have a problem do I have to ship it back to where I got it from? Can I take it to an Apple Store? How well is the return time for a problem?
