Yeah, I wouldn't buy one right now if there's any truth to the above rumors. Might be in for a treat in the next few months.
If nothing else (if the new ones aren't all that appealing for whatever reason), the current-generation refurbs will drop another chunk and that might be a way to go too.
I don't
have to buy anything at the moment, so I've got the luxury of waiting to see what pans out on the iMac front. At which point, I'll have 3-4 options to narrow down...two notebooks, or a new (or refurb) 21.5" iMac. One of those four will win the contest.
