I've had no issues with other PDAs, even having merging (not overwriting data) work fine, on many platforms.

Treo
Mac+Missing Sync (calendar, contacts), and work PC+IntelliSync (calendar, notes)

iPhone
Mac (calendar, contacts, media), and work PC (calendar) (all through iTunes)

Can the same expectations be made with the Blackberry? (I plan on using MissingSync.)

Thanks!

I can't vouch for Missing Sync, but I can tell you that Pocket Mac will allow you to sync with both PC and Mac. PC using BB DM and Mac using Pocket Mac. Opinions vary on MS and PM. I have used PM for 3 years using two BB's with very little issues. You might want to try PM before purchasing MS.

Hmm... good point. I would probably use my iPod or iPhone (*ducks*) for a music player anyway. Can't go wrong with 'free', anyhow. Well, let's wait 'till Mother's Day and see if I become a real regular here. :D

thanks.
