It may not have resulted in much of a numerical bump, but the just-released webOS 3.0.4 software update for the HP TouchPad is a fairly significant one. The big new addition is the ability to pair non-webOS phones, which will let you answer calls on your TouchPad (pairing with third-party Bluetooth keyboards is also said to be "streamlined"). It also adds a new Camera app for photos and videos, plus support for Ogg Vorbis music files, and online / offline messaging status support. Perhaps just as notably, HP is also promising "better performance" and "user interface improvements," as well as a number of other enhancements and "more robust Skype video calling." We'll be giving it a go ourselves, but feel free to share your own impressions in the comments below.
