So, my 2009 21" iMac went down a few months back. Bought a rmbp 13" but really not happy with it. It's just too small, after 4 months the form factor and more importantly screen real estate is just not working for me. As well, 256 gb hard drive is a constant issue with file management. Therefore I'm going back to an iMac. I'm not going to play the will they or won't they release something new in 2-4 months game. I need to get it now, as I really don't like using this rmbp. My option is the 21.5-inch iMac 2.9GHz quad-core Intel Core i5 with NVIDIA GeForce GT 750M graphics or the 27-inch iMac 3.2GHz quad-core Intel Core i5 also with NVIDIA GeForce GT 755M graphics. The only real difference is screen size and a minor processor jump. I'll buy refurb, so it's about 1269.00 versus 1489.00. Cost is a little bit of a factor, but doable. Primary uses are email, web, office, iTunes, movie/tv watching, photos (lightroom and/or photoshop), etc. No video games or intense editing stuff. ---------- And the fact that the 27" has user serviceable ram upgrade option.
