I'm a photographer by trade and I just bought an iMac. I grew up on PC, went to college and used a Mac, and spent years back on a PC. You have to admit...iMacs are damn good looking...Anyways, I just got my iMac earlier this week, and I'm eager to see the differences between the two while in Photoshop and Lightroom. I already have WoW installed as well, waiting for the expansion, because I've already played the game too much to give up now. I'm thinking that the iMac will hopefully work quicker, because Lightroom 4 on my perfectly good PC lags like crazy...
