What do you mean by "
limited DRM"?

I meant unlimited.
What Steam allows is for your friends to demo a game for three days. But a good game demo is enough to allow your friends to decide whether or not the game is good enough to buy.
What? It lets them play the
FULL games. As long as I sign in to my account and log out when I'm done, Steam doesn't care.
It really is. Allow me to explain:
- You must have an internet connection to "be allowed" to play the game. Otherwise you can't play the game on any computer even though you have the disk.
No, you don't. There is something called off line mode, which lets you play all your games without internet. But why would that matter. Everyone I know has internet access. Even if I had a Laptop with no WiFi I would just run my games in off line mode.
- What happens when Steam goes out of business, or the website is unavailable?
Valve has already declared that if they shut down Steam, there will still be a way for users to play their games.
- What happens when Steam decides a game has reached its End Of Life?
What? They never do that and never will.
- What happens when someone hacks your account and you no longer have access to your games?
Really? I'm not at all worried that someone would hack my frik'n Steam account.
- What happens if you try and play your game on dial-up only access? Ever try to download a gigabyte over dial-up?
Well I don't have dial-up but if I did I suppose that would be a reason not to get Steam.
- When you have completed a game and/or are no longer interested in the game, can you sell or give your game to someone else?
Actually you are allowed to gift your game to another Steam user. You could do some under the table dealing there.
- What recourse have you when Steam arbitrarily or accidentally decides you have violated your TOS/AUP and you no longer have access to your account and/or your games?
This will also never happen. Never has and I don't think it ever will.
Again, I'm confused. Merely get your music from iTunes, or wherever you want, legally, and remove the DRM. If you purchase the music then you have the right to play it wherever and whenever you desire. Simply break the DRM or download the same song from P2P. It's less risky and easier to break the DRM, though.
Why would I buy them from iTunes and then look for an illegal program to remove the DRM. I've tried it many times, but the programs always cost money or only work with older versions. If you can find a good, free program that cracks iTunes DRM, give me the link.
