One mobile operating system that has not got enough consumer appreciation, but has got critical reviews is WebOS. I’ve played with WebOS in the Palm Pixi and it is indeed the most intuitive mobile platform, in my opinion beating iPhone OS, Android, Windows Mobile and Blackberry OS in terms of pure usability. HP also realized this and bought Palm (and all its assets) earlier this year. What the WebOS lacks, is the rich set of applications that other platforms have and love from the application developers.
To fill an important gap in WebOS, Firefox is in the works to be ported to WebOS platform. The product is under development and is called PreFox. It is based on the source-code of the Mozilla Firefox for Mobile. As developer Dave Townsend states “PreFox requires webOS 1.4.5 and so far has only been tested on a Sprint Palm Pre. It probably works a little better on a Palm Pre Plus but I have no idea whether it would even start on a Palm Pixi.”
