I have a friend who never upgraded his Macs to 10.4. Now that Leopard is out, can he upgrade his 10.3 Macs straight to 10.5, without ever having installed 10.4?

Short answer: Yup.
Longer answer: You don't list the actual machines, ram or hard drive space available, make sure you have the horsepower to do the upgrade. The hard drive is probably old enough to worry about, system installs are quite the aerobic work out for a drive. Do a full backup before! Your friend is doing that already, right?

Of course... what OS can't you upgrade from an arbitrarily old version to the latest?

All retail versions of ALL versions of OSX are full installs.

Well you can't upgrade from DOS to Windows Vista, for example. Sure, you can back your files up and do a full install, but you can't upgrade to the latest version while saving your files.

So to be clear, I should be able to run an UPGRADE install and hopefully keep all the files intact?

That's changing OSs.
But you're right, Vista only goes back to Win2k. But I'm not sure I'd want to install Vista on a pre-2000 machine.
