im enjoying Android 2.0.1 (haret) on my TP2.. but i dont use it too much since they have to optimize the battery drive (its a battery killer.. 5 hours max).. also, a few big things dont work like sound thru back speaker, wifi, bt, hardware accel., accelerometer, HW3D, openGLes, post mounts (for it to charge, or for the kb lights to work, u have to have them ON, then start the android haret).. but atleast we have 3G, marketplace, kb & hard keys mapped correctly, calls, and txt working =)
but one of the main devs (Phh.......) for this android port (mainly comes from the TP1), just recieved his TP2 (from $ donations to purchase) in the mail, so the TP2 progress should be quicker for the big things.. it think he fixed the hw3d so far, and he's close to gettin the wifi working, but he said its been difficult.. but yea, thats good news for us TP2 users!
