Equip your phone with a premium word processor for $8 at Ovi
This application is made for last minute college students like me so you can take my word for it that QuickOffice is a godsend. I can't tell you how many times I was on my way to my class and I realized I have a few glaring errors on my essay or research paper. I would jump onto QuickOffice, open up a save file, fix all the errors, and find a printer in the university library to print out a new copy. I bought it when it was full price but I don't regret it a bit. For $8, I'd buy an extra copy just to give it to a few friend of mine.
