I sold my iMac to pickup an Air. Now, I'll either get a refurb'd mid-2011 or one of the news ones. I already think of Ivy Bridge as essentially a wash outside of the GPU in real-world terms, I mean we're probably talking 10% at best. The thing is, I don't know if the HD4000 is good enough for me to care. After all, it's $270. Anyone else in the same boat?
