I'd buy a MacBook Air in a heartbeat if I could get 32GB of RAM in it. RAM is the only thing causing me to turn up my nose at the M2.
If they would have released the new iMac with a bigger panel so there were options for the 27" as well as the former 21" then my mother would be rocking a new iMac next month.
I know they said up to two years for the transition but I want to transition now :)
