The only reason to hate on the TP2 is the now-dated Hardware. (And maybe the OS)

I personally think the TP2 is the best Phone Layout ever. Only a few updates and it would be Top Dawg again. Replace the MSM528MHz with a QSD Snapdragon, possibly replace the Resistive screen with either a Capacitive, Multi-touch Resistive, or Preferred Hybrid Capacitive-Resistive. Then the usual upgrade of RAM (588+) and ROM(1GB) and I will even enjoy if they left WinMo 6.5 on it. (To be honest it would be nice if HTC had an Android Variant, Windows Phone 7 and Windows Mobile 6.5 of a TP2 with a faster chipset and more memory. Imagine not having to compromise on having the best Hardware Mobile Keyboard and a decent sized Touchscreen. Only having to choose your OS flavor and be good!!!)

Only other options that could improve it are DO NOT disable FM Radio & TV-OUT. Maybe add a camera Flash and/or improve the camera, but not a biggie to me.
