Since the dawn of wireless, the roving Google junkie has faced two options: a bulky wireless laptop or a Web-page-cropping PDA. This fall, however, Nokia (nokia.com) will introduce a palm-size Internet gadget that surfs Web pages in full, albeit scaled-down, glory, anywhere. Measuring three by six inches, the 770 connects to the Internet via Wi-Fi or a Bluetooth cellphone. Think of it as a $350 replacement for that second PC. Navigate the 4.13-inch 800-by-480-pixel touchscreen using a stylus, then use the pan and zoom buttons to render the text readable even by granny standards. The 770 runs many of the applications you'd expect on a desktop PC--Web browser, e-mail client, RSS newsreader--as well as various media players, including Internet radio. That's because the 770 thinks it is a desktop PC: It's based on the same Debian version of Linux that powers millions of bigger computers. In keeping with Linux protocol, Nokia released the operating code to the open-source community, giving coding geeks free rein to develop additional applications. Wait until next year for the first new apps--most likely Instant Messenger and VoIP--or visit maemo.org to get the tools you need to modify your favorite programs or games to fit the tiny tablet.
