Yep. They rode T-Mobile Sidekick (Danger, Inc.) into the ground while putting on more bandaids, but it was a constant 9-alarm fire that didn't Microsoft didn't want to invest in seriously.

It is only getting worse, and not providing ipv6 is 'inline' with the quality of those people (well hidding behind internet).
