I haven't had too many problems with it really - aside from the god-awful bundled apps which I don't use anyway. I haven't had sleep mode working due to the rubbish nVidia drivers so it's possible i've just not seen the problem (yet) that you mention. I need to update various drivers and give sleep another go really. I know there's a new set of drivers in beta atm (for the Nova-T) with a full release due soon. I've seen some updated USB drivers from them indicating fixes for S3 mode too.
If I could get the box to succesfully wake I could easily write a small program to reboot the system just after it resumed to get round and initialisation problems - atm the nvidia card doesn't come back from sleep (black screen) so i can't see anything lol!
