I'm ready to make to switch from PC to Mac. So I went to apple.com, built myself an order and put it "on hold" in the shopping cart, just so I could think about it for another 24 hours or so. Lo and behold, this morning I received an email from an Apple Rep volunteering to answer questions, be my personal shopper, and indicated that she *might* have rebate incentives for me, etc. She gave me an 800-number contact. Does this sound legit? If so, is there any advantage to working with an Apple Rep versus just making the purchase myself on-line? BTW, I'm not in a big hurry, I'm shopping for a 24-inch iMac, 3.06 Ghz with 2 (or 4?) gb RAM -- Would consider a refurb if available. Question #2: Assuming I buy this machine, it actually looks like it's pretty easy to upgrade the RAM, but adding/swapping hard drives looks messy/scary.... So maybe I should purchase *minimum* RAM from Apple and purchase a 4gb upgrade kit elsewhere. Am I right? Thanks in advance!
