It looks like the Palm legacy has some legs yet...
A core team of the developers at HP responsible for the HTML5-based application framework upon which Palm's WebOS mobile operating system was based is leaving the company to join Google.
HP bought the struggling Palm in April 2010, and initially made a big attempt to launch products based on Palm's WebOS mobile system. However, the attempt failed spectacularly and HP pull the plug on almost everything that Palm had brought to the the company. With this announcement, then, we could once again see some fruits from the fallen Palm.
Exactly what the nature of those fruits will be is very much up in the air with Google having a number of related projects the team could be useful for. The most obvious is that Google uses them to enhance Android. Though fatally flawed WebOS had some superb core features that could transfer well to Google's mobile/tablet OS.
Alternatively we could see the expertise being put to use on Google Chrome, the company's web-app based laptop OS.
What we do know for now is that HP has committed to its timetable of releasing a fully open source version of WebOS by this September, so whatever Google gains from these hires, it certainly won't be exclusive access to the WebOS code.
