Annyone using a Bluetooth PC-Card with their Titanium? I'm looking for a adapter that gives me the functionality of newer powerbooks with built in Bluethooth. Preferably without external antenna. Like "Xircom RealPort 2 Bluethoot PC-Card" From Xircom´s site "The Xircom RealPort2 Bluetooth adapter is the first Bluetooth adapter on the market with fully integrated antenna design. This offers the user the ability to leave the card inside the notebook, as nothing sticks out. Additionally, the successful RealPort2 form factor, offers mix and match flexibility with any current or new technology. " I found nothing about OS X on the site. My PowerBook is a Rev A 500Mhz, OS X 10.2.5 /Christer
