We were then sent a new keyboard and an updated driver. We gave it another go on the hx4700, but this time, the Bluetooth manager couldn't even discover the device during pairing. We went through the same process on the HP iPaq hx2750--no luck there either. Giving up on Windows Mobile 2003 Second Edition handhelds altogether, we opted for the HP iPaq H4150, and lo and behold, it connected with no problems. We also tested it with the PalmOne Zire 72 and didn't experience any of the setup problems we encountered with the Pocket PCs.
The projected keyboard is clear and bright, although it gets a little blurry around the bottom edges, more specifically, the Ctl (Control) and Del keys. Still, they're legible and work just fine. You get all the number and symbol keys, but the BTVKB doesn't exactly mimic a true keyboard; for example, the quotation mark/apostrophe key is located near the bottom to accommodate the arrow keys. Since the BTVKB isn't restricted by physical constraints, the projected keys are large and well spaced. However, some might have trouble adjusting to the lack of tactile buttons. A clicking sound lets you know that the device is registering your keystrokes, though. If you prefer to type in silence, you can turn this feature off under the VKB menu. You can also adjust the keys' sensitivity and projection intensity, as well as set time-out limits, enable autorepeat, and more through the VKB menu.
Indeed, we had problems getting used to the lack of physical keys, and on our first try, we produced a memo rife with typos. Accuracy improved the more we used it, but we never felt fully confident or comfortable when typing documents. On the upside, the keyboard was responsive to our touches and registered every keystroke. Battery life is rated for two hours of continuous use, and we found that to be accurate. Of course, you'll get more mileage out of the battery with casual use.
