I'm a bit mystified why these systems are interesting, except that they
remove the middleman (dell/hp/ibm/etc). the hardware seems to be completely
conventional (form-factor, power dissipation, config, etc).
so the message seems to be: what's the use of TLA vendors when the servers
are not just commoditized, but also appliance-like (plug-and-go)?

that's the media spin; I'm not sure the numbers/facts really support it.
to what extent do tablets actually replace PCs? for media consumption,
certainly, and for those classes of user whose "computer" use always
was media-consumption (the email/browsing classes). for those whose
computer was always really a workstation, I don't think tablets are
changing anything. (it's easy to see why desktop sales might decrease,
without desktops-as-workstations actually becoming obsolete: they last
longer, so replacement cycles are stretching. no doubt helped by the
rather long and comprehensive recession...)

again, I'm not so sure. tower systems were always a sort of dumpy way to
build clusters, though sometimes cost-effective. I think it's mainly that
rack systems have come down in price and that most people feel some pressure
to obtain decent density for clusters (since an interesting cluster is a lot
bigger now than 10 years ago.)

but there's nothing new about these systems!
