Back in March I bought one of these Dual Phones to see how they worked out. Its a normal DECT phone that also connects to Skype through a PC. The phone rings when a Skype call comes in, and you can talk wirelessly for the range of the phone.
The phone also keeps you informed of users coming online/offline and allows you to make SkypeOut (calls to landlines), normal Skype and landline calls from the same handset. It works as described, right now it lacks the ability to pickup voicemail messages with it, but I suspect that is something that will be added to the software over the next few months. Searching the contacts can also be a little tricky with a 2 lines of 6 characters. The killer feature is the 50m range, you can make/receive calls unteathered from a PC - it won't be long before people are making hardware that allows this to be done without a PC at all.
