Heh, yes, it's a puff-piece, based on HP's publicity, not an in-depth 
review. Considering that The Machine isn't publicly available yet, that's 
hardly surprising.

Taking it with a generous grain of salt is one thing, but outright 
rejecting it is a bit harsh. I understand that HP has actually 
demonstrated the Machine, so unless they faked the demo, the basic facts 
are probably more-or-less correct.

Fair point.

But given how much smart phones get used for playing games these days, I 
think the savings would still be considerable.
