Newsflash, Android users: the Google Drive/Docs app is terrible. It's just about competent enough to read the documents you've written elsewhere, but for editing and creating new Word, Excel, and PDF documents, you need something with a little more oomph. One of the best choices out there is OfficeSuite, and it's also one of the most expensive, at $15. But right now you can - and should - pick it up for a single dollar.
I've tried a lot of the Android word processor options out there, and I can say that OfficeSuite is definitely one of the best available. I wrote this article entirely on a docked Transformer Prime with OfficeSuite. While it's not anywhere near as good as having an honest-to-God laptop in front of you, it's probably the next best thing.
OfficeSuite Pro supports standard Word, Excel, PowerPoint and PDF documents in all their permutations, and can sync to Dropbox, Google Drive, SkyDrive and more. There's a built -in file browser and presentation module. It works with a dozen languages. It's even got spell check. Why are you still reading this?
