ThinkPads are well built PC's. It depends on what you want to use it for. If you want to run games, then no, it won't cut it. However, if you're just browsing the Internet and typing notes and such in class, then it will be a great PC. Considering that any modern PC can fly through office programs with no lag, it would last as long as you want it to (take care of it so it doesn't break, but other than that, I doubt office software will evolve much more than it is now, so I doubt you'll have any compatibility issues with it).
