So GF had some issues with the 2007 Macbook today. Some issues crop up from time to time and so I thought it might be getting time to upgrade. With the price drop of the retina 13", it seems like that is the way to go over the Air. I've heard that the GPU in the 13 Retina struggles a bit to push the pixels on the retina display. But the laptop is never used for gaming, so is that ever going to be a problem for regular light usage (web, Word, excel, etc.)? All home video, picture editing, video game playing is done on the iMac, so the laptop is hardly pushed very hard. iMac also gives us access to DVD drive, so probably don't even have buy that as an external.
