chapura sucks !
activesync lets you customize the sync process. by default it's set to "compare" or something like that, meaning it combines pda and pc data. but you can set "pc overwrites pda" and "pda overwrites pc" as well, for each of the outlook elements seperately.
then again, you could mark all your private data "private" (in the categories) and set "do not sync private" on your work laptop.
although a lot of people complain about activesync, it's so much better than palm's solution.
one more thing: direct sync ! no need to press a button or anything, just pop the ppc into the cradle, and when you change an entry on the pc, it's synced right away.
