Hardware Openness Factor

BoingBoing reader Owen Williams points us to:

…. a short article asking reviewers of hardware devices to add a score to their reviews: the openness factor. For instance, when I buy this mp3 player, what will it let me do, and how am I restricted? I've come up with a simple 4-point scale of openness from crippled products that subvert standards to lock you in (remember DivX?), to complete freedom (palmOS or modern hardware).
