Maybe some people just aren't re-installing correctly. The guys that are having such random issues should try:

1 - Hard Reset your phone
2 - Let that first hard reset finish completely (no matter if your on Stock ROM or Juicy 2.5)
3 - Plug in the phone for active sync or windows mobile device center to detect it.
4 - Flash 2.6 with the RUU
5 - Wait for the entire flash and first boot up process to finish
6 - Hard Reset again and let all the customizations finish.

This will guarantee you have a fully fresh install. For me I flashed the VZW radio right after flashing Juicy's 2.6 wich performed the 2nd hard reset for me and I've seriously had NO ISSUES with 2.6 except for the landscape issues.
