Would rather have had that myself, but this was the only one I could find that would work with Boost Mobile. Went with Boost because they have what looks to be better coverage than the other pay as you go providers and I didn't want a contract with the extra charge for web browsing. Main reason I went this route was to get Square to take CC's and get away from the knuckle buster. Besides, Boost is only $55 a month for unlimited talk, text and web and they lower your monthly fee by $5 per month for every 6 months you pay on time, down to $35 per month.
It rotates but not very much larger, at least for my fat fingers.
I agree with using swipe. I'm 55 with fat fingers too, and it's easy to use. I'm not fast by a long shot, but it's very intuitive. The only problem is when you get a word wrong & it doesn't know what you want. Usually it has 3 or 4 options for the word it thinks you want. But if it isn't one of those you have to cancel & swype the word again. And I'm making it sound worse than it really is. It is really a nice feature.
