For the last 20 years, I've been a PC user and for a combination of reasons (mainly I hate the look of Windows 8 and how it works), I made the decision a few months back that my future was an iMac. As I wasn't in any rush to change, I thought I'd play a little waiting game to see what changes Apple made to it's iMac mid/top end range. Given Yosemite is just around the corner (and may prompt some small revised iMac specs) and now the apparent delay in launching the new Intel Broadwell chips, how long should I wait? Indeed, should I wait or just get on with it? Thoughts much appreciated!
