Does not do S2R and has problems with S2D (i.e. no audio or wireless after resume)... No 3D graphics, and was a nightmare to even get 2D working in something else than a slooow VESA.
Comes with Windows-only preinstalled (although Acer will refund it if you cover shipping costs to/from them so that they can remove the Redmond system).
And it's one of the few 12 inch netbooks.
BTW, newer Asus netbooks come with Poulsbo as well (1000H is pretty old model).
