Here's a list of my likes and dislikes of both the iTunes application and store.
Likes:- It's easy to use.
- It's convenient.
- It's legal.
Dislikes:- Store prices are to high.
- They'll only let you re-download your entire purchase history once, unlike Amazon. I've re-downloaded all 24 of my video purchases in my Unbox library @ Amazon 3 times without re-paying.
- The iTunes player takes a tad to long to load (even on my 1.8Ghz PC)
