Yep, remote desktop connection (downloadable at MS) is handy. When you want to have total control over your Mac familiarize yourself with Unix (eg. FreeBSD) and use the terminal (kind of warping back in time).
RD from Iridient is also very nice, especially for you since it renders Leaf files beautifully with a lot of control.
You need or want;
Stuff-it (to zip, rar, etc..)
Toast (to burn CD/DVD's and mount all sorts DVD/CD files)
MacMessenger (to MSN )
I prefer Firefox over Safari as my browser (unfortunately it does crash often at this moment when used together with PS)
You could also check out Opera
I found there are only very few applications that cannot be found in a Mac version, one way or the other.
I also like Mac because I don't find myself stirring in registry files anymore but putting more attention to actual work (You can if you really want to but why should you).
The firewire repeater is only a very small block that goes in between 2 cables. It will set you back about 25euros and really does can come in handy now & than. At least for me it does.
Another tip; The Weather service provided in the Widget standard with your Mac I found the most accurate of them all. This also does include all the other Dutch weather reporters. I always check the coming weather on my Mac. It rarely misses with its predictions.
MacOS 10.5 nicely integrates in Windows networks as well. It finds network shares easily and remembers the login credentials. Much easier than 10.4. I have not checked whether it still provides the login credentials in plain text but I guess it does. OTOH, if you have people that are willing to go that far to get to you, you have more severe problems.
