My brother has had Blackberrys for years. I thought they were okay until the later smartphones came out. I have a Samsung Epic. It isn't perfect, but I love it in general. I want to write something down, I swype up a memo. Same with a text or text draft. I want to look something up, I do. It won't replace my desktop (or laptop if used that as my main computing rig), but out and about, it's a wonder. I've been waiting for this kind of tech since the early 80s.
Android for the most part is fine for me. I can't easily customize some things....like getting rid of *Sprint Nascar*, or any of that dumb ---steaming pile of meadow muffin---, and in some cases there are too many features to keep track of/play with, but it does well enough.
I don't have any more apps than I need. I don't ever play games on my phone, or read books, or stream radio, anything stupid like that. (Mostly stupid, because those things cost money, when they shouldn't.)
