Themes are nice, but completely worthless to me as a user if the keyboard doesn't work well. I don't even care about how they make the keyboard work (they can hide all their magic algorithms and settings, etc. I don't want to tweak stuff, I just want it to work), I just want the damn keyboard to function properly. Nothing ruins a phone for me faster than a keyboard I hate. And honestly, I've tried a lot of different keyboard apps on my Android phones and none of them (even the highly rated ones) are very good. They do a poor job of word prediction and auto correct, stutter, lag, and just generally piss me off. Keyboards on my Galaxy Note I used to have made me so mad I almost wanted to destroy the phone.

Ultimately, if I like the keyboard THEN I'll be interested in themes for it. But if the keyboard pisses me off then I'll go looking for something else.

All in all, I really wish that we could have Blackberry-quality physical keyboards on Android and iPhones because these touch keyboards are way harder to use productively than something with real keys.

yeah, I agree with you. How do you think about those popular keyboard apps with good themes but useless? Those are in top now, do you think they will be gone after some time?
