Having a notebook does help to a certain extent, esp when you
have some discipline... You get to do some work during some free
time, and you don't have to squeeze in a comp lab with 3 or 4
project mates in one terminal...
I do refrain from installing games onto my laptop and heck, I don't
even have much mp3s on my laptop (got my trusty ipod and when I'm
at home, I stream from my desktop)
The only downside is that you tend to break out your lappie and go
to places like miniclip when the lecture gets boring
