It's a bit silly for me, too... I have two (functioning) Macs in the house and go for the Nexus 7 since it came. The phone I use for podcasts, much like an iPod, but I pipe the incoming nonsense. This is really weird for me.
I use Tablet Talk, and all my SMS comes to the tablet, and phone calls come in as well, but I have been ignoring those because I was reading something on the Nexus 7 when they came in. I'll get back to them later on the phone, but I know the call came through while I was flipping through the news and reading through Pocket. It'll give me time to figure out what to say, anyway.
This little thing has seriously changed my life, technology-speaking. If I can get a suitable text editor on here, for code and such, I'm not sure I'll leave it. I have become more adept at SwiftKey than I thought possible on a software keyboard.
