My 15" MBP from almost two years ago was severely mistreated in it's short tenure as my primary computer. It fell out of my car a few days ago and it is now in two pieces. I am typing this from my mother's ten year old Dell. As a Mac user for about five glorious years, this is nothing short of painful. Thankfully, I don't desperately need a computer right now. I've decided that, while I need a portable machine eventually (I'm going back to school in a couple of months), I should probably purchase a machine that sits on my desk rather than one I can toss around. My plan has been to buy a quad-core i7 iMac and doing an after-market RAM upgrade to get up to at least 12 GB. I pose the following question: would you tolerate this machine until the Sandy Bridge-based processors are implemented, or would you just take the plunge? I know it's hard to have too much foresight into the plans of a company as secretive as Apple, but is the next upgrade going to be something I regret not having? Also know that I need this computer to last me at least two years -- hopefully three. Bless me with your insight, MR.
