For the time we are waiting, here is an awesome interview with Allen Kay, the 60s & 70s XEROX Parc legend.
It is a long sunday read but very uplifting from tmo perspective.
Youyota tablet with linux and kbd comes very close to how Kay imagined his DynaBook to be imho.

To spark your interest, a short cite:
"nothing has yet been produced that fulfills the original specs for the Dynabook, including the iPhone and the iPad. In fact, mobile computers, he says, have turned out to be mind-numbing consumption devices".
