I'm also a happy customer......cause I got the 255 version ;)
However, I wasnt able to locate any concrete information on the major differences between the 250 and 255 versions of the core. I just found someone mentioning a difference in the bus frequency, and thats about it........
Not that I actually care that much (hey, I got the latest processor core, and the 400MHz version, so I'm cool

), but I would like to know what are the actual differences of the two versions......
