Another word on keyboards...
I had purchase the SlideIT keyboard a long time ago and hadn't really used it. I installed it becauseI like to use the gesture typing when on my tablet. It works pretty well, text prediction is good but no real time prediction when tracing out a word.
Not sure what the cost is now but if anyone is looking for a gesture keyboard that actually works with 4.2, this might work well for you.
If by "gesture" you mean drag your finger around to the letters you want and the word automagically appearing like with Swype, the 4.2 keyboard has that built in. With live prediction no less.
