I'm getting the 3G/Wi Fi Vita, so this AT&T news is interesting to me.
Ideally, I'd like it if existing AT&T customers could get this added to their plans for a discount. I have AT&T for my internet, which I pay $45 a month for. It'd be great if I could just add an additional $10 to it and have my Vita 3G coverage included on the bill...
Depending on what the free game is, I'd probably pay for the $15 first month, if anything, to see how much usage I'll actually be getting out of it.
The 3G would mostly be useful for me browsing/watching Netflix on the bus ride to and from work. At home and work, I'd be logged into the Wi Fi at either, so I can't really imaging my usage would be too big to warrant the $25 plan (when it comes to netflix, i'll usually watch a 20 minute show or something on the bus to kill time on my phone, then listen to music or read on my Kindle app).
I won't be picking up many Vita games at launch (so far, just Uncharted, because I'm on the fence about Shinobido, and LBP isn't out until June).
I'm dying for Gravity Rush and Ruin, but hopefully by the time they release, I'll have more money. My purchase is already creeping over $400 at the moment. I'm expecting to reach $500+ by the time I'm finished with getting everything I need.
