xPad is a handy little app for jotting down notes during class.
What school do you go to, if you don't mind my asking? I can't believe they actually charge students for WiFi access on campus...that's what the tech fee they added to your tuition bill is supposed to cover.
Check with you college to see if they have anything setup to download software. Some have nice systems full of free (for academic) editions of various programs. You might also want to check to see if your college is part of that Microsoft program (hope they are...means a free copy of Office to you).
