I will be buying a 24" iMac and am attracted to the rebates offered by Amazon.com, as well as free shipping and no taxes. However, I do want to upgrade the memory to 2 Gigs and possibly the video card, and am wondering if that's possible thru them. Is it faster to buy from Apple? I imagine thet they charge tax. I'm hoping that my printer, an Epson 740, will work (Epson says it will) otherwise buying an Apple and getting a printer with a hefty rebate is attractive. I also would probably get .mac for $30 less and imagine that it's available at Apple only. I've never bought anything this sizable from Amazon and wonder if anyone has had a good experience purchasing a Mac there? I've never talked to a human being there either and that makes me nervous. I live in NYC and could buy from Tekserv but I'd have to pay taxes and carry the thing home on the subway. Of course they also have open box deals that might work out spectacularly. I've covered a lot of ground in this post but I really am curious about buying from Amazon and if it's possible to change the specs there. I always do my own painstaking research but I've gotten some wonderful help here lately and so value this community's collective opinions. Thanks in advance!
