Google acquired mobile design company Milk Inc. last week. However only half the team was brought in to Google. The other half was the engineering team, which included Amber Reyngoudt and David Peck.
The reason why Google did not hire the engineers is because they have plenty of engineering talent. They wanted to hire design talent. This is why Kevin Rose was brought in. Rose has joined the Android team. Reyngoudt and Peck will be re-launching Skull Ninja, a startup they founded before joining Kevin Rose at Milk.
