A detailed test can be found in Notebookjournal incl. Lots of readings. There is already said everything in principle, which I can only add my own personal experience. I had tw for the gap. Mobile phone and 15 "notebook / desktop PC with 22" netbook searched. After hours of searching it was clear to me - it should be a 10 incher with a matte, light-heavy display and a slightly stronger graphics chip to be.
As there are currently not many candidates, only turned the question Intel or AMD. I opted for the AMD variant, for my usage profile (browsing with Opera, videos with VLC and in our games a chess program) I'm even out with one GB RAM. To go the annoying Umschalterei a variant with Intel N550 plus ION2 at W7 Starter out of the way, came only one version of W7 HP and 2GB in question, which is then equal times 100 EUR more expensive (see Asus 1015PN).
Nett is the VGA and HDMI port for an external monitor, but you should not have exaggerated expectations of the performance pipsqueak. For Photoshop and video editing course I sit down at the desktop PC with the 22-inch model. For me he is the ultimate companion traveling on the plane or in the train. 5 stars because it is designed for making super there his task.
