Well, personally, for portable computing, I don't think the netbook can be beat. You can easily take one plenty of places I wouldn't ever take a £1000 "Ultrabook" (like, in a rucksack or tail pack on the back of my motorbike), nor would I let the kids take an Ultrabook *anywhere*.
Just because some people prefer something more than a netbook, does not devalue the netbook, just different kit for different uses (and I don't think you can really compete with the size weight and price of the netbook, unless you really do need a portable desktop replacement).
Personally, I think for pure portable web surfing, a tablet is tops, for all round useage and portability, a netbook, a full blown laptop for portable desktop replacement and/or an Ultrabook for the same, but more portability/less weight, but with much greater cost, and of course, a desktop for permanent convinience and high-power processing requirements and/or, anything else you want to do.
Right tool for the job! :) (if you don't want/haven't got space for a desktop, then IMHO, everything else is a compromise of one sort or another...)
And: "No one wants to use desktop Linux on a tiny screen with a cramped keyboard and even worse trackpad. They just provide and poor overall experience. They're not "good old" anything. They are and always were a bad idea. Just a way for OEMs to keep volume up during a recession."
Well, apart from myself, I can think of quite a significant number of people I know who would disagree with you! :) Linux runs well on netbooks, but I note, XP just about, and Win7 is like wading through treacle! :(
