As you have most likely already heard, Microsoft has launched Microsoft Office for iPad... yes, iPad. And it's beautifully made and very feature rich:The real Microsoft Office apps for iPad are here!
However, I think there is another story here that is even more interesting. Office for Windows 8.1 is currently a bit of a joke. It's doesn't really work with the Metro interface (or whatever that is called today), and it very much seems like a half-baked product.
So how can they create this beautiful iPad app that is completely touch optimized, but they can't seem to do it for their own Windows tablets?
To me the answer here is organizational friction, which is something we see in so many companies. The iPad was a new market, so the developers were free to innovate and do the best job possible. Windows is an existing market, so the developers had to make sure not to piss off any of their existing customers and department heads.
Or as I wrote a couple of days ago about startups vs corporations: "A big company fear losing their existing market, so they see change as a risk. Startups fear not getting a market, so they see change as the solution."
Office for iPad was developed like a startup, while Office for Windows 8.1 was developed like a big company. One is great, the other kind of sucks.
