Superficially, Amazon has little to do with open source in the enterprise. But as the largest and highest-profile online retailer, Amazon plays an important role as an indicator of where things are heading. So I think this is actually quite significant:
Amazon MP3 has been around for several months now. And it’s doing pretty good. Decent amount of press coverage when it hit the stage. Decent song selection, all with decent sound quality. And just about everything is decent with the all-DRM-free program Bezos & Co are touting out in the cloud.
And now the company’s gone and done another decent thing with is music download service: it has opened its doors to Linux users.
Amazon wouldn't be wasting resources on this if it didn't see it as relevant for the future. Now all we need is for the music download service to be available in Europe....
