WebOS can also synchronize data on various HP devices, so the address books, e-mail and other applications data is automatically kept in synch, HP says.

The tiny Veer phone has a slide-out QWERTY keyboard, 2.6-inch 320x400 touchscreen display, and a touch area for navigation. It supports Wi-Fi, Bluetooth, Flash and GPS, and includes a USB port and audio jack, as well as a 5-megapixel camera. The phone has 8G bytes of storage and the same amount of memory as the Pre2, and can be used as a Wi-Fi router for up to five devices.

The more powerful Pre3 has a 3.6-inch, 480x800 display and a 5-megapixel camera that shoots HD video with stabilization. It also has a forward-facing camera for video calling. It runs on HSPDA+ or EVDO networks and has a Qualcomm chip running at 1.4GHz. Both phones are compatible with HP's Touchstone charging dock.

HP also emphasized social-networking attributes for the devices. The tablet's photo app displays photos from a user's Facebook, Snapfish or other online account, and comments posted on Facebook photos can be displayed on images when they are opened on the device. The address book will include LinkedIn and Facebook contacts.
