But I did find the software I wanted from apple (mainly iWork) was much cheaper than Office and it too was easier to use.
Easier to use, but lacking in many features people use (especially Numbers > Excel).
Just thought i'd add that Apple have, in my experience, made Mac OS 10.5.x updates a buggy, tiresome experience. Permissions tend to get ripped to shreds unless you use the big, 600MB combo update. Tiger on the other hand was perfect.
This explains why you'll have to pay for a non-buggy Leopard (or "Snow Leopard") in something like 6 months time!
