Found on Everything Pre about the Palm Countdown showing (currently) just over 3 hours until the future of WebOS to be revealed (noon PST).
This actually interests me way more than the latest batch of Android tablets. WebOS had a unique interface (definitely not me-too iPhone-like UI) and was sadly hobbled by horrible (IMHO) hardware and (as I understand) horrible carrier contracts. I'm intrigued to see what they do with this.
Also isn't this OS going on the "iPad Killer" that HP announced last year that was going to run Windows 7?
Update2: A few quick thoughts. They have the Veer (tiny smartphone) the Pre 3 (bigger, "business" phone) and the Touchpad. I'm not a fan of the slider keyboards, and I hope that the Pre 3 doesn't suffer from the horrible "feel" that I had from the original Pre. Also the 8/16G sizes are ok, but compared to the 16/32G on the iDevices... well, I like lots of media lets just say, but I know I'm not the norm.
Also for a company that claims to innovate, this shot looks really similar to something familiar.... Their "stacks" way of doing multitasking and showing running apps is pretty awesome though, as does the "Exhibition mode" the phone OS goes into when you put it down and the fact the tablet and phone work nicely together.
These are available summer/fall, and that's a long time. In theory the iPhone 4s or 5 and iPad 2 will be out by then, both with probably bumped specs and more refinement in the OS, meaning that while the new Palm/HP warez look good for now (maybe even a bit ahead if you look at the tablet having front/rear cameras), in 6 months when they actually see the light of day, they could be fairly behind the Apple/Android leaders of the pack.
However it's great to have a 3rd (or 4th if you count Windows Phone 7) horse in the smartphone/tablet race.
