I have an iMac coming today and now I'm having 2nd thoughts about the model I ordered - this is my 1st Mac coming from PC for the past zillion years. The model I ordered was the refurbished mid 2010 - Refurbished iMac 21.5-inch 3.6GHz Intel Core i5 processor - I paid $1269 ! Now I'm thinking I should have ordered the new 2011 model - 21.5-inch: 2.7GHz 2.7GHz Quad-Core Intel Core i5 The new 2011 model features a quad core and the refurbished one is a dual core -- the price on this one is $1499 How much better would the newer one be -- the truth is, I'm coming from a 4 year old Dell PC dual core with 3 gigs of RAM and really, it's plenty fast for me. I don't mind spending the extra couple of hundred bucks for the newer one - but is it gonna make that much of a difference -- I'm planning to order another 4 gigs of RAM to add to the refurbished one if I keep it -- I also go the 3 year Apple Care extended warranty for $119 -- my net cost for the one coming today is $1495 including tax, expedited 2 day shipping, and the 3 year extended warranty. Any help here would be great - I'm new to MAC since this is my first one - I normally keep my computers around 4 years before getting an upgrade. I don't do any gaming if that makes a difference ! Thanks in advance ! If I want to return it for a swap - will I run into a hassle ? I NEED A QUICK ANSWER - FED-X WILL BE HERE SHORTLY - Thanks !
