I'm sending my Macbook back for a refund because I don't like the screen when playing games are watching videos. Otherwise, I love it, especially the size of it. It's easy to carry from one room to the next and I really like using it on my lap while I'm at my couch or chair. Typing is easy too since there's not a huge gap from the end of the notebook to the keyboard, allowing me to comfortably rest only my wrist on the notebook when typing. I plan on using my refund money and purchasing the Pro model since I think it'll be perfect for fixing the screen issue I have the with the Macbook. My only worry is that the extra weight, and more importantly, the extra mass will make it much less portable and less comfortable to use when on my lap, or when typing. I know there's not a huge difference in size, but sometimes it's hard to judge how things feel with even the slightest differences. So, do you all feel that the Pro model is very much a portable machine that's easy to use on the go, or when you want to use it on your lap, or while laying in bed? My last notebook was a 17" 8 1/2 pound monster, so I know it'll be much easier to use than that thing. I just hope using this Macbook for the last 2 weeks won't make the Pro feel too bulky. Any thoughts you have are appreciated.
