When Microsoft opened up the MSN Music Store the other day, there was a comment about Apple and how their system is "closed". This was given as a reason that MSN is better.
"iTunes has done a great job of helping to elevate the [digital music] market," said Christine Andrews, lead product manager of MSN. "We're different because Apple is a closed system. If you want Apple, you have to use the iPod. A lot of people want choice and we offer that." [macnn.com]
So let's see. My choice is use iTMS and an iPod, or buy a whole second computer in order to use the MSN Music Store. Let's be honest, they're both closed in different ways. IMHO MSN's is more closed because I can't even use it on my computer. Though I wouldn't hate Apple if they opened up access to their DRM a little bit. Given their market share I think they can afford to let people use a few other players. There is still a market for flash players that aren't that expensive.
