For myself, I have no use for text prediction, or MSExchange.
I'd like Alien Dalvik in principle, but confess I don't have it installed on my X daily driver, so I wouldn't really miss it.

I had community port on my X and on Gemini, and the only downside I really had in both cases was BT would never connect to my car. When the official SFOS for X came along, BT started working straight away. Not sure on the Gemini - I'd already given up on it when the official version came along

In other news - looks like F(x)tec took their money from my account this morning
