Had the Atari, the Psion 3, the Libretto and the first EEE PC 701.
This category is completely misunderstood by manufacturers.
I want an ultraportable machine that I can use anywhere, is relatively solidly built (no stupid Ultrabook breakability) and I'll pay a premium to get a proper usable machine. I don't care about resolution (up to a point) and I don't care about the thing looking poncey. Bigger screens? I've got a 40" monitor that I'll plug in to the thing if I want a big screen, this is for working, not watching rubbish or playing games on.
God knows why the PC companies haven't made netbooks with decent specs. Why can't I have 8gb of Ram and a decent chip? I'll pay for it.
The closest I've seen is the HP DM1, which when you put an SSD and 8Gb of Ram in it, is a great little machine.
