OS X upgrade compatibilty?

[VintageMac]

I have an eMac G4 1.25 running 10.3 and a MacBook on order. I am thinking it would be best to have them both running the same OS.

Should I simply buy the 10.4 upgrade for the eMac now?

Or

Should I wait until 10.5 comes out and then upgrade both?
Will my eMac handle 10.5?
Can I upgrade both computers with one copy or will I need to buy two.

Thanks for any counsel!

The eMac should run Leopard fine.

Leopard will install on both computers from the same disc but there is only one license for one machine. If you want to stay within the terms you can purchase the family pack for a bit more which I believe has 5 licenses.

The family pack gives you 5 licences but costs less than 2, so that's the way to go
