Avakin Life, is getting a new update soon (In beta testing right now on Android), the update brings with it a new interface that i personally find much better to use than the old interface, below is some screen grabs from my Android tablet.
I tried going on Avakin on my Kindle Fire HD a couple of weeks ago, and I didn't really care for it. A large part of it was the interface. Also, not to be rude, but it was kinda like a cheap version of Home. It was a bit difficult to play on my Kindle Fire (I did have to delete a bunch of apps first), but then it's not really for playing those kinds of games. Maybe if I get an Android Tablet, as I'm hoping for Xmas, I'll try it again, especially with this new interface. But personally, I like to play those kinds of games either on my computer or PS3.
