Very nice. Pretty much everything I read was a net positive for the product, the only quibble might be the price but of all the things you can change in the future that is easiest to change :-).
I was intrigued by the music keyboard, not because I think the Surface is the instrument of the future, but because I think there is a market for a device which can easily customize its input experience like that. I have thought for a while that future test equipment from Tektronix or Agilent might look like that but with a scope control panel and a dock for attaching probes.
Like the 2 position kickstand, the one we got at work to do testing on that was annoying. I bet Surface 3 touts an infinitely adjustable one :-).
I think the ARM/x86 messaging is pretty spot on as well, Microsoft is playing the "its just windows" card pretty hard and dropping the RT moniker was smart too. Most consumers could care less about instruction set architecture. And what happens when Apple makes an Air with the A7 ? Will Apple have the 2 x 2 matrix (iOS/MacOS)(ARM/x86)? and Microsoft the 1 x 2 matrix (Windows)(ARM/x86) ? I'd think the latter long term is easier to message and less confusing for customers. If they go all Ubuntu like and create a Win 8.1 phone experience then there product / os vector is 1x3 (Windows)(phone/tablet/laptop).
That said, for me it reinforces the notion that this is the year of the Linux desktop. I recently had the experience of using a USB serial cable that worked under Linux but not under Windows 7. That was one of the signs for me that perhaps Windows was ceding the development workstation business (or at least not paying attention to it). That should be good news for folks like System76.
