I was wondering if Mass Effect is worth $20. I enjoyed Oblivion and KOTOR, but I don't want a game that has TOO much to do. ( Oblivion/Morrowind)

Also, has anyone got the the new Apple OS 3.0? I have an Ipod Touch 2nd Gen, but waswondering if it's worth it. I feel that's pretty low of apple to charge $10 for what looks like 1 or 2 small updates put together.
