Completely agree, but you forgot the best bit ...
... the Wyse laptop. Staff that move from multiple offices may no longer need laptops, because (of course) all the Wyse 'desktops' are equivalent. But for people who need to be able to work from home, airports or anywhere with a public Internet connection, the Wyse laptop provides all the functionality you described. And when (*not* if) the laptop is lost, stolen or strayed, there's no local data to worry about and no need for complex and expensive encryption schemes
