Cordless IP Phone with Wireless Router Function

Softbank BB to Market Cordless IP Phone with Wireless Router Function

Here's a nice product idea. An ADSL modem combined with a Voice over IP phone, and a wireless  router.
Simply connect to the DSL, sign up for the SoftBank BB service (in Japan), and you have a fully functional  VoIP service, as well as instant connectivity for any computers with 802.11b networking cards in them.

That the unit comes with a separate wireless VoIP handset is just an added bonus.
