Well...
First, some disclosure. I own an HP laptop, a self-assembled desktop, and semi-remotely manage another desktop and laptop, all running W7. One of them has a Mint Linux partition for dabbling in and making the desktop into a FAH beast. I own an iPhone, and would like to get a slate that comes with or I can put Android or Linux on because standard USB connections are good. Oh, and I'm across the pond.

My first thought was snark: Respect for the dead?
I'd like to think it's really an understanding that "security through obscurity" has already been panned enough around these parts.
Those that just want to do work are going to stick with what they're used to using until it stops running. Then they're going to get it fixed or get a new one, and keep going. This is part of the reason Apple is gaining ground, people will pay to be able to be lazy ("it just works"). Anyone that doubts this should consider the cruise and tourism industry. The other being that they're actually employing some good designers, who have learned that you can make a computer case from more than just plastic with a metal bezel.
Now taking bets on when the glass-coated wood inlays show up. I seem to recall an article here about a company selling glass spray that makes surfaces essentially dirt and bacteria proof. Should remove most wear issues, yes?
