I'm a photographer but I've been dabbling in video. I need a more efficient workstation. I'm starting to browse the market for a new Mac and have always wanted an iMac. I had been waiting quite some time for a full new model which we just saw. However, since I plan to use this computer for the next 3 to 4 years, I don't think a first version is a good idea. However, I've waited for so long that I'm about to just pull the trigger. I'm currently running a 2009 17" MacBookPro. I've upgraded it numerous times extending its life to today, where it's pretty much maxed out. My latest upgrade was a 200GB SSD and replacing the Super Drive with a 1TB HDD. It's beginning to have issues such as unresponsive keys and uneven back lighting. I can keep it sputtering along for another year if I wanted to but should I? I don't follow chip technologies much these days so perhaps somebody can offer me advice. Where are we in chip cycles? I got the impression that the new iMac uses existing chips. When are the next gen Intel chips due? What are the odds of a retina iMac this year? Touch screen? My gut tells me to wait until OSX's 10.9 is released to developers and that the code could give us a hint at what Apple is planning for its desktops into the future. By then we should likely also know what the new Mac Pro is like. Is it a Mac Mini on steroids? A maxed out iMac? Please help me pick my next Mac.
