Have one. Works fine. Check you don't have problem with a yellow bias to the bottom right hand side of the screen.It was a problem with some of the early iMac's A grey background will show this up. If it looks good then I'd buy one ( again) Not a fan of the wireless keyboard I miss the numeric keypad. You may want to get a wired one, if you find you can't get on with it. Also treat yourself to a magic mouse ,if it doesn't come with it. Also think about increasing the RAM to 8Gb. Not something you need to do straight away though
