I still purchase most all music on CD's. Why?
- Wave files are "lossless"
- Failsafe backup copy
- Can sell, trade, give to others
Which is why I also purchase movies on BluRay, the evil file format that Apple still
does not support. Apple claims that Sony is to blame, which is a half-truth. Apple wants us to purchase digital copies for their own reasons.
I remember once upon a time when Mac had technologies prior to PC's and normally by default. With "less expensive" PC's, one had to purchase an adapter for Ethernet, a graphics card, a sound card, a CD-ROM, etc making their computers actually more expensive, especially when you consider that you had to fight to get everything to work. This is in part why I switched over to using Mac's full-time back in 1995.
However, business models have got in the way of what's best for users. So, use a Mac and purchase products on disk if you want to pass them on, sell them, trade them, etc.
Apple will most likely win this battle, as they will claim that people are not forced to purchase music and movies from iTunes. When you purchase anything from iTunes, you are agreeing to their terms. However, users can win their own battle by purchasing media in non-digital form -- CD's, DVD's, and Blu-Ray.
