Word has it that Cisco is looking to buy Nokia, as a way to jump-start development of wireless network applications. The buy would be a good move for the networking giant. Wires are a thing of the past. True, Cisco needs to still sell wired infrastructure, which will continue to be a cash cow. But the future is one without wires, and Cisco needs a quick entree in. Linksys and existing Cisco wireless businesses are only a small start. Cisco must get into the unwired world in a big way, and Nokia may be the fastest way in. Can we expect routers built into cell phones? Sounds outrageous, but don't be surprised if that happens some time after the sale. Travel routers are already popular, so why not build one right into a phone?
