The whole point of a laptop was take a desktop anywhere we want. Right? What has limit the laptop portability? Well, BATTERY LIFE!!! Grant, it is still portable, but it deters many from using as much as we like. Screen size is also a limit. 17 inch is just too big!! 15 is perfect. 10 inch is ok. Anything smaller is just too small. So, I am hoping the new macbook pro has a 10 hour battery life. The iPad is almost perfect for me.
