Right - and show me the app I can install on all those various places Linux is deployed. Show me the consistent UI experience across them all. It's not there.

Right - and show me the app I can install on all those various places Linux is deployed. Show me the consistent UI experience across them all. It's not there. You can't. My point isn't about the the underlying OS (the kernel) itself, which has gained huge traction. It's about an experience to the end-user and the developers that's consistent. Not having to pick a .deb, .rpm, to know what libraries are/aren't available etc. That's my fear for WebOS - that many different versions will get built. Some will support WebGL, some HTML5 etc. (These are examples, please don't tell me the do/don't exist already - I wouldn't know). The whole fragmentation thing people talk about with Android, but to a much greater and detrimental degree.
