Interesting sign of things to come: Microsoft has bought a reference design for a wireless PDA phone from a Canadian company called Intrinsyc that supports the Smartphone OS, and has an integrated GPRS/GSM modem; Ethernet, serial, and USB ports; Bluetooth; a four-inch color LCD touchscreen; digital camera; and Compact Flash and SDIO slots. No word on what Microsoft plans to do with the design, or when it might go into production.
