Finally, found how to sync between Playbook browser (Dolphin) and my pc (Chrome) !
Found out about Dolphin browser (rated three stars but it seems like a topnotch application).
Noticed there are no add-ons currently available for Dolphin on the Playbook but that is besides the point. :)

Guide on how to sync between Dolphin on the Playbook and Chrome browser on a pc:

Not sure if both types of sync work (Dolphin only and Dolphin + Chrome) but for me, syncing just the Dolphin browser will do fine.
To sync, all I did was press sync on top of the Bookmarks column in Dolphin (to get this column to appear, slide from the left-most part of the browser an inch or two to the right. Once I've done this, I then click on the Dolphin add-on in Chrome (on my pc) and choose sync.
Hope this helps people who had trouble syncing bookmarks between the Playbook and a pc.
