At Google most in-house projects are infrastructural, and if you look at the scale at which they run and the fact that there&#x27;s basically nothing that even comes close, they are wildly successful. You could also say Android was in-house, because what they bought is not at all what they ended up shipping. What they bought looked like a Blackberry rip-off, what they ended up shipping was an iPhone rip-off. And let us not forget Ads, the in-house system that has dominated online advertising for a decade now.<p>But I kind of fail to see what any of this has to do with Microsoft. :-)
