I got to use a HP Mini 210 with a dual-core Atom and 1366x768 10'' display. Other configuration was standard: Atom N550, 1GB RAM, 250GB hard disk, Win7 starter.
I must say the HD display made the experience quite a bit more enjoyable than the retarded 1024x600 displays most netbooks come with.
The keyboard was also excellent and the machine is quite slim and looks great. Battery life is quite long too (at least 6+ hours). All this for $299.
Overall quite happy with little machine.
I wonder why more netbooks don't come with this display resolution. People keep saying that tablets are killing the netbook but I think its the artificial limitations such as the display resolution and limited RAM as well as poor design choices in keyboards or batteries by some OEMs were also responsible for the netbooks decline. Intel GMA probably played a part too
edit: Changed demise to decline
