For about the first 2-3 days seriously though about 21.5 but 2 friends and some research later, don't know wtf I was thinking and by Jan hope to have a giant 27' porn box eerr iMac!
I figured go big or go home. I am stoked I got the i7 as well.
Wow a lot of people are getting the 27 inch iMac!
I figure within the next few months I'll find a way to connect a DVD/BR player and a cable signal, so it will be a great all-in-one product.
There is a solution available right now, if your devices are HDMI: Get a standard HDMI-to-DVI cable, which is available dirt cheap on places like monoprice. Then get the Atlona DVI-to-mDP and connect it to your iMac through Target Display Mode.
Something for a direct HDMI-to-mDP should be coming soon.
just received my 21.5 and it is one really nice machine. I couldn't be happier.
