Lets first talk about Linux.
Ubuntu 11.10 runs GREAT on the nettop. Its fast, you don't need a HDD because with linux you can boot from SD card. I also think the Wifi driver for linux is better then the windows one, at least dealing with n. XBMC runs fantastic my HD rips run fine but I took a uncompressed bluray rip today and it did stutter a little bit I would say about 90%.
Flash is pretty much out of the questions. I don't think the flash plugin or the AMD linux driver are up to the task. Even normal SD flash skips a bit.
1080p HD can sometimes stutter.
Now onto Windows.
The OS is fluid, just as fluid as my i7. Flash works damn near perfect. You can watch 1080p or any other resolution you want. drivers and a cinch to find. Windows update pretty much takes care of everything. XBMC is screaming fast and drivers are updated constantly.
Windows cost money
No SD Card install.
