Hi Joseph!
The smalltalk image is portable. You can use a same image on windows, unix, or mac. I develop on mac, but when I go on holidays, I continue to work on the same image using a windows. Then, when I come back, I continue the development on mac.
I remember that once Andrew mentioned some problem with little and big endian, but I can not give more info about it...
