I have both T-Mobile and Sprint, and I have unlimited everything with T-Mobile. I use the Sprint line for personal use, and was going to upgrade to the Evo or the Epic in November, but now I'm thinking maybe I should get the Samsung Tab instead, and use it as a tablet and sometimes as a phone for the few times when I need to make phone calls. What do you all think? Would carrying a Tab as a phone make sense? Especially since I already have another phone with another carrier that works good for phone calls?
