yeah i run a motu 828 on windows XP and it has probably crashed maybe once in a year

and i use it at least 4-5 hours a day solid

BUT dont get a dell laptop to use with the 828 - it aint compatible (i made the mistake) dell have some ****ed up driver in ther that shafts the audio playback and neither motu nor dell could fix it!!! (there is a warning somewhere on the motu website i think)
