The iMac is rumoured to being updated in June. If you need a Mac now, you will be absolutely thrilled with it and it'll be over five years before it becomes obsolete, if you can wait until June then good things will come! Mountain Lion is due later and it will be a $29.95 upgrade, so to me that's a small price to pay to enjoy a Mac sooner rather than later.

Are you backed up??? If so, why? Psyllium Fibre is not free but will do wonders!

I'm watching for the new iMac updates closely.
It has been about a year now, and the new Ivy CPUs are being delivered, I can't see it being more than a few weeks before updates on iMac and MacBook Pros.
On my five year upgrade cycle, I have one more year to wait, but I'm hoping that they update this spring and next spring before I jump on a new one.
I wonder if by May 2013, the whole thing will see a major redesign, it's been about the same for 5 years now. Could they bump the 27 to a 28 inch screen? the only big change recently is the Thunderbolt port.
