Do I need to install my palm 4.0 software and am I best to use the palm desktop software as I do on my PC or should/could I use it with Entourage?
Yes, you have to install software. Go to
www.palm.com and download the software for Mac.
Also, is the palm connected in any way to ical and the address book that sits on my dock?
Yes, it is. You will have to download (free) iSync from
www.apple.com page.
I use m505 with TiBook running OS10.2.6. The only drawback is that there is no Avantgo for MacOSX (yet?).
Good luck,
Mac-iek
