Just two things different, from my knowledge: the CPU speed, and Cardbus was enabled on all of them from the start, because they managed to fix whatever hardware issue they had on the production run of the 2400c/180 units. Oh, yeah, and as Ralph mentioned- a Japanese Unicode keyboard. Ah! Well, this may be only cosmetic.........but the caps lock had a light in it! I can't remember if the normal japanese keyboard that I have has this feature, though. I will look at it. Good luck with it :-) __________________________________ Do you Yahoo!? Yahoo!
