Hello, Looking to get a new iMac. The current one I have is the 2005 G5 model, great little machine. Anyway I digress, I am aware that a new update for the iMac line is due soon (late 2010?) but can we expect any significant updates apart from a speed bump? Just to add a little meat to the bone in terms of usage generally I'm not going to be using it for anything strenuous or complex, just email, internet, iTunes, iPhoto and Microsoft Office. Thanks all.
