Hey all, I have a Macbook Air 1.7 GHz Intel Core i7, 8GB of RAM, and Intel HD Graphics 5000 1024 MB. I do a lot of photography and have big programs running like photoshop, Lightroom, etc. I'm tired of working on an 11" screen, was thinking of upgrading either to an iMac 27" or going with an external monitor and connecting my Macbook Air to that, would just have to buy a wireless keyboard (does anyone do this?). Can I get some recommendations? would be nice to hear from others who have their Macbook air's connected to an external monitor too. thanks!
