Antonius..if you have a good internet connection you can install Creo 3.0 trial in abt 45 mins...that is the time it took me with a 4 Mbps connection.
my trial is getting over....other than the align option in "freestyle" and the " optimize surface" in boundary blend..i do not remember anything new in Creo 3.0....
we have a "style" license at office..but rarely use it...so not much experience...
