So I've been eyeing on some android keitais for a while.. but before I make the jump, I was wondering how they work. I use a good chunk of social media (facebook, tumblr, snapchat, twitter, etc.) I know they aren't touchscreen but have the touch crouser instead. how well do those apps work on these phones using the touch crouser. Is there any possible way to install the play store instead of the other apps stores they reccomend?

Kyocera gratina 4g, kyocera digno, and sharp 601 sh/01j are just a couple I've been eying on. I've also been looking at some korean flip phones but some of them are hard to get other than the galaxy folder.
