Late enough to miss the market window, delivered only a fraction of the promised features, less than the Danger Sidekick which it was supposed to build upon.<p>The official Windows phone unit was doing its best to kill the Kin, it had to switch to Windows CE, <i>it was required to support Exchange</i>, and a lot of the code supplied to the Kin group, especially for Exchange, was in horrible shape.<p>Ah, and another example of this sort of bad Microsoft behavior: When they bought Danger, they ignored its contractual responsibilities to T-Mobile and expected to immediately repurpose Danger&#x27;s technical employees.  Oops, T-Mobile refused to put up with that, and those employees had to spend some time developing the last Sidekick models (and all this had a morale crushing effect, above and beyond that of being absorbed by Microsoft with its stack ranking el. al.).
