Since HP acquired Palm last spring, it has been revamping Palm's webOS mobile platform. Recently, we tested the HP Veer, a smartphone that runs on the updated webOS2. Apps appear on the Veer's 2.6-inch touchscreen as large cards that you can flip through with your finger. You can run up to 15 apps simultaneously and see up to three of them on the home screen at once. During our test, the Veer, which runs on AT&T's speedy 4G network, downloaded Word files quickly and responded well to taps. On the downside, HP's App Catalog is a bit anemic. Cost: $99 with a two-year contract.
