Links for Tuesday March 8^th, 2011

• Used iPads Selling Quickly Online: It's kindof amazing how well older, used iPads are selling. It seems like there is a big market for sub $400 iPads. I'm wondering if Apple will ever address that?

• Playing Music Better: Tim Bray lodges some complaints about iTunes (which I do not share — iTunes is working great for me), but the comment thread has lots of interesting discussion, including pointers to XLD and Decibel.

• Did Google Pre-Emptively Block a 4G iPhone on Verizon?: Interesting speculation that the "open access" rules that Google lobbied for 3 years ago, might affect a potential Verizon LTE iPhone.
