The keyboard has become an extremely subjective thing. Some people swear by Swype and would never use anything else. I personally never adjusted to it and stopped using it because I didn't find it to be very accurate. I also felt like it only saved a tiny bit of time, and that time was then wasted when it would select the wrong long word and I'd have to erase it and start over.

I like Swiftkey because I've been able to fairly quickly adjust to how it predicts text. I've become very good at knowing when it will predict the right word and when I shouldn't bother to look up at the suggestions. For common phrases it just flies along, and for less common words I just keep on typing. I use it as an assistant and not as a crutch, and I like that I have that option. I tried using Swype as just a keyboard and something just felt wrong about it.

Anyway, like I said it's very subjective, so if you like the stock Android keyboard then that's great!

I have to admit that on-screen typing hasn't quite reached the quality of the iPhone, but it's getting there as these companies make better quality capacitive screens. Larger screens should help a lot too, and I can't wait for my own phone to have a nice big screen
