Metamorphosis fascinates us humans; just witness Kafka and his cockroach. We prefer, however, the stylish switcheroo offered by Motorola’s MPx Pocket PC Phone. Open it sideways, and its keyboard and screen resemble a mini-laptop. Flip it open as you would any cellphone, and voilà — the keyboard’s ready for dialing. The built-in Bluetooth, WiFi, camera, and tri-band GSM aren’t bad either. www.motorola.com
