It's useful when you need it. I have a heavy laptop I'm using and it has wifi in it. I can't wait for my own computer.
I have a really small laptop around the size of an iPad. It's really awesome but too bad I can't upgrade the RAM past 2 gigabytes.
Ya... I wonder who's face that was. Because maybe the person who owns that face is wondering why he posted his face like that, and is now famous for being used for weird pictures. The things we can think of.
