Microsoft’s acquisition of Sidekick-developer Danger - which it first announced back in February - has finally reached completion, according to an announcement today.  The company will now be consumed by Microsoft’s Premium Mobile Experiences (PMX) team, situated within the Mobile Communications Business (MCB) and responsible for making Microsoft’s mobile devices - particularly their cellphones - more palatable to individual consumers.  Danger co-founders Matt Hershenson and Joe Britt will both take up positions under PMX VP Rox Ho, and the company’s staff will continue to work from their existing offices.

Ironically, the news comes shortly after I suggested that Microsoft might buy in some GUI and interface expertise to increase the acceptability of Windows Mobile in the face of devices such as the iPhone.  While at the time I suggested the existing WM skin developers behind Point UI, Danger’s experience with a local handset/remote server model could be seen as the consumer version of Microsoft’s Exchange system.  Considering the developing demands of the consumer market, it wouldn’t surprise me to see a Danger-led multimedia handset, built around a Windows Mobile core but with a home-user version of hosted server backup and messaging, announced soon.
