I've recently had awful problems with my macbook that ended with it having a two week stay at a repair shop to the tune of £300.
It's come back with Snow Leopard (great since it went with Tiger) and a new hard drive and more RAM. Unfortunately, it's lost iWork which I rely on for household records, correspondence etc.
I've got the iWork disk ready to install but am really worried it will just cause problems all over again. It will be okay won't it?
