For those who enjoy Swype, Android is a no-brainer. I believe that those who don't like it are just too stubborn to get used to it. They don't understand that it gets better as you go along. I can type fast on a full QWERTY landscape keyboard, but I can type faster with a full QWERTY portrait Swype keyboard, and that's no exaggeration. In fact, my buddy who has an Epic 4G just uses Swype instead of the full keyboard for that very reason.
Apple needs to release a Swype knockoff before I consider an iPhone in the future...single letter typing with FUCKING AUTOCORRECT as opposed to Swype is night and day.
