I wasn't too happy about this either, especially since I used Microsoft myphone and it wouldn't port my contacts.
What I did (& think has already been suggested here by others) is:

1) Used MS Outlook 2007 x86 & installed Windows Mobile Device Center 6.1 (2010 x64 will not work) to connect & sync my TP2

2) You can now export your contacts from Outlook 2007 to a .csv file.

2) Go to Hotmail & import the .csv to your contacts.

3) Last, sync your wp7 with your hotmail acc't.

Note that you can also use gmail to import / sync your contacts & you should be able to find a trial version of 2003, 2007 or 2010 (x86 only). I would guess you can export to .csv with open office as well although I dunno how you would sync your contacts...

Hope that helps.
