I think Java/Android is doomed to PC History ...
I hope, maybe this explains it to you, http://www.ubuntu.com/phone
Some of my favourite bits are ...
"Ready for your phone, With all-native core apps and no Java overhead, Ubuntu runs well on entry-level smartphones — yet it uses the same drivers as Android. "
or " A fast-evolving app ecosystem We’re working closely with selected partners to get their apps onto Ubuntu; Facebook, Twitter, Dropbox, Evernote and Amazon will be available at launch. "
and the biggies ,
"And at the high end, Ubuntu paves the way for a new category of superphones, with a full PC desktop accessible just by docking the device to a monitor and keyboard. A handheld PC is the future of personal computing — true convergence"
" And because it enjoys the full capabilities of Ubuntu — including kernel-level control of every app — it puts the security and manageability of UNIX in your pocket" "
I hope anything based on Java, is gone, if a device can run Android, why not have Linux instead ?
