I think the device market is under-rated by the traditional IM clients. This example from Ascalade (VON brochure) is a residential dual phone that can connect with both VoIP clients and PSTN simultaneously. Note this one doesn't work with Skype yet, it's designed to work with SIP solutions. Still embed Skype in the box and who needs a computer?

When could we see a Skype version? Perhaps sometime early in the new year. What's the achillies heel for all these devices? I see two currently. They haven't yet solved the text chat messaging opportunities, while many are stuck with memory problems when you have more than 80 - 100 buddies.
