Slashdot directs readers to a Firing Squad article that looks carefully at eleven mistakes that FS feels Microsoft made designing the Xbox 360. The complaints at Firing Squad aren't at all "omg, the games lock-up!" and instead look at issues like how Microsoft could've changed its own music distribution system to compete with the iTunes' model while using the Xbox Live infrastructure. It's an interesting read, to say the least.
