Have you tried a ChromeBook? The current hardware is a bit slow, the software is still very much a version 1, but in my experience it's like an iPad for "real computing": because it has a keyboard you can use it for emails etc, and in my opinion it has a similar "joy factor" to the iPad - it lets you do what you want without overloading you with superfluous junk.
As someone that has had to deal with far too many Windows machines in the past, a Windows laptop with bolt-ons simply isn't the same experience. Perhaps if you put it into "kiosk mode", set Chrome to boot as the desktop, disabled the task bar, disabled running all other apps etc. But what you've got there is no longer Windows as far as the user is concerned, and so why would the hardware manufacturer pay Microsoft their $15 for the OS license?
Just like with Apple, there's possibly a price premium at the moment, but the scary thing for Microsoft is that - unlike Apple - there's no inherent reason for a price premium with a ChromeBook. Google could actually subsidize the price.
