Wait, because is not so simple... the IBM sold "pero no mucho" his hardware's area, because still continue giving support to hardware sold by Lenovo, and this is very different of HP while has Hurd as CEO, that was keeping the HP in a good road. Is not good read and believe "blindly" in everything.
In regards to the context of this closure being against the backdrop of (the then plan) of getting rid of the PSG, interesting article about IBM:
Maybe I'm wrong; and usually I am, but I believe that there is 2.1.0 for Pre Plus EU; so, not all problems come from HP, but include your carrier, too.
Considering that the Pre and Pre Plus were "abandoned" in Feb 2011 and left with 1.4.5 software, there has not been an overwhelming owner loyalty base for WebOS.
Other "bla, bla, bla" trying to blame the SO, forgetting completly that the iOS was very raw in begining, Android was more than raw begining but his companies has invested to spread yours SO and Devices.
Another take on this story from an insider:
With the early webOS releases, there were scrambles to fix issues on software and hardware, and then a classic second system syndrome kicked in. Many shortcuts were in place, so people wanted to go in and fix those problems and “build it right”.
The rise and fall of webOS is an epic tale; webOS != Web OS on Dion Almaer's Blog
"I remember going into Sprint stores asking for a Palm Pre and being told “hey, get a Blackberry instead!"
A PERFECT example that the problem was ADVERTISING, and not SO. In described case, claps for RIM...
