But maybe you like the 10-inch form factor. Maybe 7-inches is just too small for you. Or maybe you want a tablet to use for work - documents, spreadsheet, or other text entry. For that, the Nexus 10 is pretty perfect. Ultimately, here's an ideal scenario: Nexus 7 for gaming, casual reading, and social networking. Nexus 10 for "serious" web browsing and getting work done. But there's a chance you're not going to want to spend $600+ on a pair of tablets that will do the same thing you can already use your computer for. Then you have to make a decision.
For me, the choice is clear: I'd buy the Nexus 7. If I need to work from my tablet, I can. It's not ideal, but it's not broken, either. In my opinion, the benefits of the Nexus 7 simply outweigh those of the Nexus 10. That's not to say the N7 is better at everything than the N10, because it's not. I'd rather watch movies on the Nexus 10. If I'm going to spend an ample amount of time editing documents, I'd rather do that on the Nexus 10, too.
