Rob Pegoraro of The Washington Post says that pricing and restrictions are the biggest problems with Apple’s iTunes Music Store. “The iTunes Music Store’s success hides a couple of unsettling trends. One is pricing — a lot of albums now exceed the store’s customary US$9.99 price, and a few even exceed their cost as CDs in a store. The other is compatibility — though a variety of consumer-electronics devices could be made compatible with iTunes music files, the only one Apple permits is its own iPod digital-music player.”
