After much fence sitting, I decided to cancel an order that I had placed for a base 21.5", after considering the new 27". The only reason I wanted to upgrade my 2009 24" is because I wanted video input, the led screen & SD slot. The problem with the new iMac is that my MBP is a 2010 model, so it wont work with the new 27" target display mode. In reality, my 2009 24" c2d 2.66 is fast enough, has a 1tb hd & 4gb of ram... So im not getting much more with the refurb 27" besides the 3 things listed above, but the price in the refurb store is killer - $1049 (!). Im kinda wishing I could get the new machine, with its shiny quad core processor and GPUs, but it would defeat my only purpose for upgrading.
