I would say that as you aren't planning to play any games or use any intensive applications like that then go for the laptop.
If you were then definatly desktop.
Although depending on how long you intend to spend on the computer, for instance on the net etc I wouldn't like to be staring at a small laptop screen for long. You could always though buy a bigger monitor if you wanted to plug in to the laptop as they are cheap, or get a docking station.
