I would love a modern version of the N900/N810. If I could get one with a recent ARM processor, good slide out keyboard, and running a more desktop-oriented Linux install (meaning more hacking/developer friendly than just Android), I'd be seriously tempted. Sadly, I assume the current component prices would mean it would be too expensive to be realistic.
Funny I was a supporter of their devices I bought both phones, laptop, tablets... Issue is the software man no drivers. Like the e-ink tablet had a great design/screen but the brush stroke was ass would leave dotted lines as you drew then it would render solid on lift up.
I'm complaining even though I'm not writing the drivers myself I get that.
