| Review summary | The HP iPaq rx5900 Travel Companion delivers a sleek all-in-one navigation, productivity, and entertainment device to mobile professionals; we just wish it had better battery life. | On paper, the Mio DigiWalker P550 looks to be an attractive gadget for the mobile professional, combining the capabilities of a PDA and GPS into one device. However, its poor battery life and subpar navigation skills tell a different story. | Info unavailable | Info unavailable | Though not necessarily worth the price for an upgrade, the Nokia N810 Internet Tablet brings some nice additions to the mobile Web browsing device, including a full QWERTY keyboard and integrated GPS. |
