So I bought the stock 27 inch and while its beautiful and the screen is nice, I've already had some semi-serious issues. The main issue is laggyness. What I can do on my stock early 2008 MBP is causing pretty bad slowdown especially on a new mac. I bought this to play poker on and while my macbook pro 2008 version can have both programs I use at the same time, my tracking program, a browser window open and itunes open, this is having trouble having 1 site open, and if theres any flash on any of the webpages, my computer comes to a almost standstill, and forget about music, any sound coming out sounds distorted and pixelated. Oh yea the MBP was running itself plus a 24 inch monitor at 1920x1080 with zero problems as well. I don't want to have to return it, but if it can't even do half of what my mbp does with no issues, its a pretty sad replacement :-/ I'm going to try to re-install the OS, but I don't see how that will change anything.
