Looks very similar to devices such as the Intel Compute Stick. Sure they aren't very powerful and I wouldn't be recommending them as a general purpose computer but they do have a place for certain applications such as kiosks, digital signage and media playback situations or for users with very limited needs. I'd think of them as more like a more powerful x86 version of the Raspberry Pi instead of as full blown PCs.
It's the sort of chip you'd find in the latest Windows tablets and they are generally pretty quick - My tablet has the much older Intel Atom Z2760 and while it is easy to push it to the limits, it's generally okay in terms of performance for note taking, web browsing and IRC.etc.
Dave - Pretty sure this would be more powerful than that Netbook as it also has an Atom but likely a much newer generation one.
