Are Web tablets and e-books becoming commoditized already?

Hewlett-Packard's throwing one into the box with a new $399 all-in-one inkjet printer it's calling the Photosmart eStation.
The printer includes a Web browsing tablet with WiFi and a 7-inch diagonal screen. It's pre-loaded with applications including Facebook, a music player, Barnes & Noble's eBookstore and Yahoo mail, search, weather and messenger.

When it's not being used around the house, the tablet sits in a dock on the printer and works as a control panel and digital photo frame.

The Android-powered tablet apparently doesn't let you load applications. It sounds like a new version of HP's Dreamscreen lightweight tablet/photo frame that appeared in 2008, more than the full-fledged slate computers that HP's expected to release later this year. But this one comes in a printer bundle for under $400, and it may be good enough for some people.

Here's a video from Laptop magazine, trying out the eStation:
