Quick note - I don't recommend CM alpha 3 at the moment in stock form. This will likely change when alpha 4 comes out, but at the moment
stock alpha 3 is fairly buggy (it feels even more buggy than alpha 2, actually). Instead, I
highly suggest everyone upgrade to the xron-ified version of alpha 3 found here:
[vB1.2][CM7 XRON-ified][CM7.1 Alpha 3][Updated 12/7/2011] - xda-developers
For those of you who are using alpha 3, you may notice a current slew of bugs and an interface that leaves a bit to be desired. Good news is, there's a developer who's been fiddling with the alpha and making it "better". Better youtube support, better video in netflix, better responsiveness, better support right out-of-the-box. Install this and you'll automatically have the right google apps installed for your tablet, e-mail will work out of the box (with notifications when you receive new email), google marketplace will work out of the box, google talk will work out of the box, the keyboard is more responsive, everything looks nicer (it uses a nice honeycomb theme), and battery life is significantly improved. Better yet, it's being updated on a weekly basis and improved upon all the time (incorporating new alpha releases of CM7 as well, so when alpha 4 comes it will also be incorporated into the xron build - the cyano devs have said that alpha 4 will still be a CM7 build, so this is very likely something we'll see soon).
Just do it. You'll love the change.
(ASSUMING YOU ALREADY HAVE ALPHA 3 INSTALLED, OR SOME OTHER ALPHA ANDROID)
Step 1: Download the file at the link above. (grab the most updated version, right now it's vB1.2 as of 12/9/2011)
Step 2: Toss that file onto your touchpad (just put it into USB mode and toss it on the device).
Step 3: Reboot the touchpad into clockwork management.
Step 4: Perform a backup of your current device (there's a backup/restore button, make a backup - it'll only take a few minutes and it'll allow you to return the device to the way it was if you for some odd reason prefer to).
Step 5: Perform a factory wipe (the option is there in clockworkmod).
Step 6: Choose the install from zip option, and install the xron-ified zip file.
Step 7: Reboot into android and enjoy a superior experience.
It's the best android experience available on the touchpad at-present. Give it a shot and I think you'll agree.
