For the time being, if you want to check out the latest version 3.0 of webOS, you have to do so on a TouchPad, just as Android Honeycomb is relegated to tablet status. It looks like HP may be considering plans to bring the OS (or at least parts of it) to the smaller screens of smartphones, with the revelation that the webOS 3.0 virtual keyboard contains a mode for smartphone use.
When scaling down the screen size in the webOS developer emulator to something more appropriate for a smartphone, the system automatically replaces the virtual keyboard with one that has a layout optimized for a smartphone-sized display. Further digging uncovered two sets of resource files, one for a full-sized keyboard, and one for this petite version.
So far, the smartphone-sized keyboard has only been confirmed for portrait mode, but it may be possible for it to work in landscape as well; investigations are continuing. None of this makes it a certainty that webOS 3.0 will come to smartphones, or even its virtual keyboard, but it’s clear that at least someone at HP has been working along the lines of that possibility.
