A standard data plan is about $30 a month, so it's not like you're getting a deal there. No one offers family data plans yet, though Verizon supposedly will as a next step in the data plan competition.
So then you pay an extra $30 a month, and if you want a gaming phone, you're paying for those games. Plus it's small yet thick and dim, if it's the Xperia.
Another thing you'll notice is the battery life. You're probably used to leaving your cell phone here and there, and charging it every couple of days. Not with a smart phone.
If you want a good smart phone, there are better. If you don't want to use one, $30 a month adds up, though it sounds like you've gotta money to blow.
go Droid or go home IMO
