HP just sold the beleaguered remains of webOS to LG. According to news reports LG plans to use it for smart TVs.
In other words LG is going to give webOS a chance to fail in a third market (first 2 were smartphones and tablets), one which I don't expect to exist in 18 months.
This operating system was Palm's failed attempt to regain some market relevance when it was launched in 2009. HP then bought Palm on the strength of webOS, bungled the launch of new hardware running webOS (proving HP was even less competent at mobile devices). After the death of the Touchpad, webOS was supposed to be released as an open source OS some time in 2012 - but
that never happened. so far as I can tell it hasn't gotten much further than versions that will run on the Nexus 7 and on the Nexus 4.
Today's news hardly rates more than a footnote. Frankly, when there were no tablets running webOS at CES 2013 (like I expected) I assumed it was completely dead. Never mind that in late 2011 HP was still planning to release another tablet running webOS; without widespread adoption webOS was DOA.
