Reasons for waiting on the new iMac: too expensive for older technology, lack of USB 3 means spending more money on thunderbolt (or slower USB2), and let's face it -- I like new technology! Reason I jumped ship and just purchased a 2011 27" iMac: cannot do things on my current macbook that I want to be able to do NOW (not in 3 months), back to school deal, AND next weekend is tax-free weekend in my state (which won't happen again until next August). So 2011 iMac now and save ~$300 or 2012 iMac in 3 months without any discounts... well, $300 is a decent savings, and in my mind offsets the cost of this expensive older tech. Of course a new iMac with the back to school and tax-free savings would be ideal, but that's just not happening. And I need the computer now. I'll pay to use it for the next 3 months and then put it up on ebay if the new model is something I really want -- with what I'm saving now, the hit shouldn't be too bad. Anyway, if I wasn't going to make good use of the iMac over the next few months I would totally keep waiting... but I need it now so I bought it.
