OK, first impressions.
Holy hell does ICS run beautifully on the touch pad. Butter smooth and I love the new style and functionality. The most recent list of apps is particularly nice, shades of webOS... It also boots really really fast after the first boot. Notifications are great too - again shades of webOS. Haven't run into any trouble with apps either - runs Google currents beautifully, for example.
The downsides.
3 random reboot already. This on a virgin touchpad install. No warning, just an instant reboot.
Typing seems to want to insert periods after many of the words I type. This is making posting this very. Annoying. Maybe fixable with a different keyboard...
The touch pad. Doesn't. Seem to be. Charging. Properly. On the. AC cable. (See what I mean about the periods?)
I don't recommend this right now, but guys, when they sort this out its going to be fantastic. Absolutely fantastic. I'm sitting here using this -knowing- that once the quirks are repaired I'm going to be using this non-stop.
