iPhone 4 here. That's part of the reason I use it so much -- it's so easy to use and a pleasure. I can't stand my pc now lol. My typing on a full keyboard has actually gotten really bad -- I'm super-fast on my iPhone, tho.
I mean, if not for the eye thing, I think it's better for me than a pc -- doesn't have me bending forward or sitting at a desk for hours on end. But this eye thing is really bad

Also, I asked the doc if I got the surgery, would my continued use of the iPhone cause the same problem again, but she didn't think so.
Will have to see what the specialist says, though. This is all so bizarre for me. I never imagined getting an iPhone would do this to me. And yet I'm too attached/addicted to give it up, of course.
