Apple recently seems to have taken a hint from Microsoft, and turns to be evil.
They have sent cease-and-desist letters to people who try to figure out the hash in the iTunesDB database that is part of every iPod.
I have three iPods, a 1st gen Nano, a 2nd gen Nano, and a 2nd gen Shuffle. I am using Linux, and Linux only. iTunes doesn't run on Linux, so I have been using gtkpod to put music on my iPods.
I am ready to buy a 4th gen Nano, but I need to be able to use it under Linux. Apple's strong-arming of independent developers prevents that.
So, I'll be spending my money somewhere else, until Apple comes to its senses. In these economic times, they should be happy that others try to increase the market for their devices, instead of sending in the lawyers...
