To answer your question....
Yes, the 10.5 developer preview does offer an upgrade option.
Because I just had to play around/experiment with the darn thing, I got ahold of one I wasn't really supposed to have and gave this a shot.
In my case, I ran into problems where my Address Book app crashes with the spinning beach ball every time I run it now. (Actually, I got into it once or twice and had it work properly, but ever since then - no such luck.) Tried repair permissions and all that, and deleting Address Book's pref files, but didn't help.
It also appears that Apple changed the way services are installed? I tried to get the "Rumpus" FTP server to work on the 10.5 preview and it kept getting errors about not being able to install the daemon - though everything else seemed to be ok.
Otherwise, most things I've tried with it so far seem to be working pretty well. I noticed I couldn't get stuffit expander to behave properly, however. It just says it will take 2426573657 hours to decompress a file and freezes up.
All in all, it's neat to play around with a little bit - but I don't think the 3rd. party apps are quite ready for it. I'd tell you friend to make a full backup so he can go back to it after playing for a little while.

My friend wants to do this. Even though I keep telling him
it will probably break his iBook, he wants to do it. And I still dont know why he would
But anyways, he wants to know if there is the option to upgrade from tiger to Leopard in the installer. Can you help my idiot friend?
