To each its own...
Like W says above, every glove has its hand... or a car its driver... or a netbook its owner!
From all those *I have seen* I must say that the 901/1000 would be my choice, followed by the Wind and the Acer as 3rd.
Like I commented in the SSD article, the one I will end-up buying for me will have a 10" screen, >16GB SSD, >1GB RAM and most importantly >8h battery. It just has to be priced right and allow for each upgrade and customizations. The 1002H might fit my specs, but price and battery life are still to be assessed.
I still haven't seen the NC10, but unless it comes out with an SSD it might not be an option for me... unless one can replace the disk with a sata ssd without voiding the warranty!
