Oh really?
> Open source is not a very big selling point to the masses.
No, but it enables other manufacturers to hop on board and create an ecosystem. Nokia had Intel and others in their corner...
> WebOS was open source and better than Android at the time, had good reviews, but it flopped miserably.
It wasn't open source until it had already failed. Plus it never felt as though HP really cared all that much about mobile devices, they were a huge monolithic entity making too much money on desktops, servers, etc...
Contrast this with Nokia, the world leader in phones (including smartphones) for quite some time.
Also, at one point Symbian held 70+ percent of smartphone market share, Nokia obviously did know how to create an ecosystem.
> No, it was Nokia's board that hired him in the first place and approved all his big decisions.
Obviously a mistake on their part. Corporate boards don't always make the best decisions, though in theory they should.
