Huh?
"The phone market" may not be looking for another contender (not sure how you can speak for the entire phone market... but that's another show), but I was! I was ready to plunk down cold hard cash for a Pre3 to go with my 32G TouchPad... I love WebOS (to me, it's the most efficient phone/tablet OS in regards to multitasking and built-in apps (read: android) -- for example, the email client is "da bomb" -- without being too simplistic (read: Apple-OS - Sorry, I work on a lot of cisco gear, and IOS says "Catalyst 6509" over "iPad" to me...) the facebook client was great until Apple whined that it was better than what was available on the iPad and Zuckerdood stopped improving it...
No, I'm not trying to be a "hater" - I've used all three and they all have their strengths and weaknesses - A lot of people prefer iPad's single-task orientation... nothing wrong with that except I personally don't like it. Android's lack of unified task management is painful compared to WebOS (If it's running, it's in a card. If you don't see a card, it's not running) - Granted, I'm not keen on WebOS's "If it's not a newish HP printer, you're not printing to it." Blech. Hopefully going Open Sauce will let me print to my PCL-speaking (and also PostScript-compatible) Ricoh in short order.
P.S. Almost all of the people that I knew that had a WebOS phone that was forced to move on to a different platform (dead hardware, better wireless service, etc.) say that they much preferred WebOS and wished it was better supported from the wireless carriers and HPalm.
Oh, and don't get me started on your ludicrous Linux statement... you are aware that Android (and WebOS) is Linux-based, right? And there is one market where Linux is mainstream - the server market.
