The downside of the Nexus 7 is that document creation is not as simple as on a laptop. However, there is a cheap and easy way to do simple document creation on the small screen. The basic Write: Tablet Notepad/Journal application from Google Play Store at $2.99 does a decent job. The document is easily readable. Then, ideally, you will need an adapter to plug in a regular keyboard or just use a bluetooth external wireless keyboard. A female USB 2.0 to male USB micro adapter for a regular keyboard costs less than $1 on Amazon. Either keyboard disables dictation. (You can use dictation with the Nexus 7 screen keyboard.) There are lots of choices of sizes in USB keyboards. I tried a less than $10 rubber rollup, but liked my bluetooth better. Once your document is finished, it can be saved by Write to Dropbox, shared by EMail, or printed with the PrintShare app. I published this posting direct to this website with Blogger direct from Nexus 7.
