I have CM9 on my TouchPad as well. I keep installing it, then uninstalling it. I forced myself to leave it installed this time. It has been installed for more than 3 months this last time around. I even update it every time a new nightly comes out, yet I only have less than a week's worth of use on it. I have a ton of apps on it yet I hardly ever use them. The problem with Android is the usability. WebOS is just a ton easier to use, especially with Luna CE installed. I have thought about getting a Nexus 7 or Kindle Fire HD to replace my TouchPad with. I just can't seem to get myself to buy one.
I have CM9 on my Touchpad for dual booting to Android. I still prefer webOS despite a couple of issues - 1) Text is sharper with Android - I need to see about replacing default text in webOS. 2. Android has a newer flash version which is smoother and quicker.
My brother picked up the Nexus 7. I didn't think I would like the size but it is quite portable and web pages don't look at all bad on it.
Enjoy them both for the benefits they provide.
