I usually take my laptop to class to take notes, surf the web and read/edit documents. It's not a super heavy device (rMBP 13") but it definitely adds weight to my already packed messenger bag. I'd like to start using my iPad a bit more and leave the laptop for the heavy work at home. I know the basic apps that work well cross platform (Dropbox, Evernote, Pages) but I'd like to know if any of you guys have a particular app that you just cannot live without, wether you're in college or not. There's a lot of apps in the Productivity/Utilities section in the app store, but I don't feel like spending $10 on each app just to try them out and realizing they won't work for me. I keep reading that 'Things' is a great app, but it's super expensive, and you have to buy the app on each device. I would spend that money in a heartbeat if it truly does facilitate organizing things, but I just don't see what's so different from a free app like Evernote. Any thoughts guys? Recommendations? Any 'hidden gems' out there? Thanks!
