I have been running first Windows XP and then Windows 7 Home Premium on my Asus 1000H, the latter for almost 2 years now. When I got my 1000H, probably 3 years ago now (or more), the first thing I did was upgrade to 2gb ram (the machine's max) and a 7200 rpm 500gb hard drive. I've been using this laptop in a corporate work environment, running dual monitors (laptop and 19" LCD). I use mostly Browsers and MS Office type applications, do some occasional vba coding, and once in awhile run Chief Architect Home Designer 9 and photo programs. It works well, though its not a speed demon on the graphics and photo editing programs. I usually have several browser pages, a handful of Outlook windows, a couple instance of Word and perhaps Excel or Adobe Reader open at the same time. I am running aero, but you can turn that off if you want. I can run Youtube videos and stream Hulu on it without stuttering. As a side comment, I'd say get a physically well built netbook. I've taken mine on 4 extended European travel vacations to handle digital camera photo storage and processing and the original Asus eggshell design has held up well (hate the fingerprints though :>).
