yep, my ipaq 3955 says compaq on the ppc itself and hp on the standard case that comes with it
i love my ipaq. becareful though as you will get dependant on it. i ran into a software conflict once (installing something that should have been on C: on a different partition) and was without my ipaq for about a week.... i was worthless without it!
you will love the ipaq if you get one!
