I have a problem with my current self built machine http://www.tomshardware.com/answers/id-3148576/gigabyte-bootloop-bios-autorecovery-post-lights.html. So I am considering getting an iMac to replace it. Was wondering if a new iMac is coming out soon? When is the likely release? Is it worth the wait - or is there nothing really new? Of course if I have to wait, I will need to repair the existing machine, or rely on my work Macbook Air.
