I finally got around to installing Android (CyanogenMod 9 - Android 4 ICS) on my TP.
Had a couple little hiccups but still didn't take long. I could do it from scratch now in less than 5-10 mins, it really is dog simple. You can probably do it in 30 mins when I save you the hiccups, including reading the details.
Dual boots so I still have webOS, but man is android snappy on this thing, I should have done this long ago. Only issue so far is Android doesn't reconnect to my non-SSID-broadcasting network after reboot. Likely just an issue with my particular network setup. WebOS was left untouched and works as it did.
Most impressive after using it a bit is the microphone search, I guess which is on par with Siri. That and the robust app store, looks like Apple's.
Well worth it, if you have considered doing it, go for it. I'll post the specifics for a quick install if you're interested.
Resistance was futile...
