I want an iMac... I can get a used - like new iMac 21.5" direct from Amazon themselves on Amazon.co.uk for £745. "New Apple iMac 21.5" All-In-One Desktop PC (LED Backlit Screen, 3.06Ghz, Core-i3, 4Gb RAM, 500Gb HDD, ATI Radeon HD 4670 graphics, Slot-loading 8x SuperDrive (DVD±R DL/DVD±RW/CD-RW) (Launched July 2010)" Only i3 though... That's an inpulse buy but it's from last year? Does that matter? Now that's tempting. But no keyboard and mouse though. Will that come with a warranty? I won't get the free Lion upgrade though, right? Does this model have a thunderbolt port?
