The Kensington Vo200 Bluetooth Internet Phone is a neat little device that fits and charges in the PCMIA slot of your laptop. It can be used to make calls over VoIP services like Skype, MSN and Google Talk. The phone has three hours of talk time and 30 hours of standby time, and also blinks when you have 10 minutes of talk time left. The fold-out design is particularly cool. Unfortunately, the product page says it only works with Windows XP.
The VoIP phone is listed on several vendor sites, but it isn’t selling just yet. When it comes out, it will be about $90.
