First, are there rumors that a huge major update for all Macs is in the pipeline in 2012 that I should wait for. Or is that mostly just hogwash? I want to get an older 27" i3/i5 iMac for ~1200 if possible. Otherwise I'll have to settle for a mere 21" one. Also, is there any possible way to connect a PS3 to an iMac (I really want to play blu rays on it somehow)? Is it possible to swap out the hdd for a SSD on the older iMacs or the newer ones? Any recommendations on what would give me the best bang for the buck in terms of iMacs (older or newer) is very welcome. Thanks in advance.
