where are you buying these things? i haven't seen any specific "netbook" machines that are higher than WSVGA. you have to reach into "proper subnotebook" territory for significantly higher resolution.
someone sat in a typical IT department that's just had a delivery of brand spanking new, middle-spec, Windows 7 preinstalled.... and 1024x600 rez netbooks
have you any idea how tidgy stuff looks at 1280+ resolutions on a sub-12" screen, anyway? Also, 720 pixels high is not enough for the 21st century. Once we get towards 800, then we're talking.
I'm happy with my 1024 wide BUT 768 high (12") laptop screen by the way. Vertical resolution is FAR more important for a whole range of apps that don't fall within the small range of a/ watching movies (which is what we're all doing on our computers all the time, right?), b/ playing FPS games (big whoop on a netbook) or c/ the latest multi-columnar version of Outlook... which is best at 1366 or wider anyway. This old lump still works fine. I had the option of getting a 1280x720 one when buying it... probably would have dumped that by now.
Word processing, powerpoint, spreadsheets, internet..... on my two monitor setup, all those live on the secondary, 1280x1024 display. And quite often image editing too, as once you take toolbars into consideration (PARTICULARLY ribbon ones), the remaining workspace is roughly 4:3, 16:9 or 3:2 landscape photo shaped. Office 2007 on a netbook screen is painful to use.
