For those who have tablets... do you guys have one with mobile data or just tether to your phone? I'm looking to get the Nexus 7 and don't see the point in spending $50 for the option to have mobile data and then another $20+ a month for data plan (I don't have shared data plan - I have unlimited Verizon 4G plan).<p>It's seems there are apps available to tether and as long as I'm not using the phone and tablet simultaneously, speed wouldn't be impacted?<p>Curious as to which is the better option to choose. Also, I know my unlimited data plan won't last forever, so perhaps getting the one with mobile data could be useful (so that if/when I go on a shared plan I can have my Nexus 7 join the party? Although, I suppose I could STILL just tether... no?)<p>What do you guys think?
