So where are the netbooks that should exist by now?

I want a new netbook — my cheap'n'cheerful Mini 9, having had the crap beaten out of it on a daily basis, is slowly failing in new and exciting ways.

The netbook form factor is perfect for me. But the visible hand of the market means Moore's Law hasn't done its work, so available netbooks are not 4x as fast as 2008, but about 2x for the same price (~£200) and build quality (cheap'n'cheerful).

Does anyone have tips on where I can track down the sort of device that should exist by now?
