I am still getting a handle on the software. I did not think the other version sync'd anyway nor does this. You read from Mobile into Kies or from PC, then you save to one and/or the other. That's not syncing in my opinion. Palm desktop did true syncing for over 10 years. What every you changed on either sided got updated when you sync'd.
As for 2.0 the Contacts definitely appears as does other areas of multimedia after you connect to the Galaxy. the selections appear much like it does in the ITunes interface and the device shows there the same way. It does handle managing and importing data much better (VCF files anyway). Cleaning them up on the PC is not to bad. I kept a backup since I am not certain if its merging correctly the one time did it. It appears to be a full re-write of the software. Too bad there is no manual for it.
HTC has no such software and a good PC Desktop PIM is very important to me having used one for 15 years or more from the 1st Palm PDA 128k and I still use it all be it updated version of the software but the data started way back then. Hopefully it will improve in time. I will have to look to see the calendar etc is there as well.
PS: Thanks for your comment, I am primarily on the Telus Fascinate thread now but posted here as well since this should be the same for others as well.
