I have a Touch Pro and I can confirm that it is H E L L to transfer contacts.... Winmo associated to 1 Outlook "presence"... everything goes to that one outlook account.... If you should plug the phone is on another PC.... the phone wipes ALLES! - I've had it happen to me a few times. If you only have one outlook accounts, then it's nice... Outlook and WinMo is sync/harmony....
I can't wait to get back on the Nokia boat.... so tired of HTC and their crappy phones.... the only thing that's nice about them, is that their phones are very good for enterprise usage.
I have my phone sync to Outlook, and then get the Google Sync app, which will then sync Outlook to gmail contacts (and calendar).... the other option is to export all the contacts to a csv file, then import it back to the Nokia PC suite....but if a contact has multiple lines, i.e more than 3 emails addy's, multiple numbers, etc.... the csv import doesnt do them all, so you could lose some numbers.... best bet is Google Sync to preserve them all.... when you've finished with the backup, check the contacts to make sure it's all there.... I don't trust HTC or Outlook.
