Yes I did! I installed Windows 7 on the eeePC. Yeah I know, I am not the first person doing it, I just thought it would be nice to try, so I found this excellent post and followed the instructions to the letter (well, not exactly but who does anyway?). The reason? Well, why not? No seriously, I was dying to find out how well (or not) it would perform.
I used an external DVD drive, so I cannot verify whether you can port Win7 on a thumbdrive or not, but I have no reason to doubt that. Be careful to install the vga drivers (click on the above link for more info) with compatibility for windows XP. I chose Windows XP Service Pack 2 from the available options and it worked fine.
So, how was it, I hear you ask. Suffice to say that I returned to eeeBuntu. Although Win 7 are supposed to offer support for SSD hard disks, my experience was slow and painful. I am not sure, since I kept 7 for about half an hour before I re-installed eeeBuntu, but I think that the user experience was worse than XP (and that makes sense). I tried to bring all graphics down, disable indexing, play around with some settings, but that didn’t change much.
