After upgrading to Leopard, I bought the MS 6 upgrade to continue using my Palm TX with my MacBook. Things work, but I swear that about 75% of my syncs now end in the Mac application crashing--crazy. I almost always send my crash reports in, so I hope a 6.0.5 update will appear soon.

Startup time for v6 seems to be very slow, which adds to frustration following crashes.

Though it's Apple's fault, the program can no longer mount external memory cards on the Desktop, something I loved under Tiger.

For syncing a Palm under Mac OS X, this is really the only game in town. It does a competent job, and if you use J-OS to use Japanese on your Palm, the program will handle Japanese text syncs well.
