Software compatibility issues?

[Raist]

I am planning to buy a Powerbook in the US; as I live in the EU, my future OS upgrades (beginning with Panther) will be done in Europe.
Does any one of you know any compatibilty issues between geographical zones?
:confused:

Only the power supply and modem...
Usually the modem is not "cerified" in other countries, but most of the time they work normally.
OS X (incl. Panther) is "all languages fits on CD's"... so to speak :)
So the CD's are the same in every country.
Only the boxes it is sold in are in different languages, also the Apple Hrdware Test CD.
