Ahh - ya its really not a big deal at this point. You don't have to plug in or anything of that nature.
Though I will say - iTunes on a Mac is FAR AND AWAY better than iTunes on a PC. If I had a PC only and had to use iTunes regularly, I wouldn't like it either.
Luckily, you don't have to. I use iTunes at home as my default media player to stream things from my iMac (which acts as my central media hub) to my AppleTVs. iTunes works really well in my opinion.
Don't you start this again!
Unless you buy your content from apple you really do need iTunes!
