Hi, I currently have a pretty decent desktop PC running 64-bit Win7 Ultimate. Absolutely no problems at all, everything is running super smoothly. However, I'm really tempted to jump in a get a laptop to either supplement or replace my desktop entirely. My options are - 1. Keep the PC and get the white unibody Macbook as well. 2. Keep the PC and get the 13'' Macbook Pro (maybe refurb). 3. Ditch the PC and get the 15'' Macbook Pro i5. My uses are fairly light: web browsing, writing, occasional gaming, photoshop, and occasional AVCHD video editing. Which do you think is the best option?
