Small wonder...
Really. First, Google (as well as most Android handset makers) is somewhat ignoring business needs. There's no kind of FS encryption of any sort, support for things like Cisco SecureIP VPN is missing, managing business email accounts with deep hierarchies of folders with the Android email clients is a bad joke, the Android market is a crapfest, there're hundreds of devices to evaluate and every single one of them might be replaced with a totally different model three months later with no updates anymore for the one you bought in large numbers...
Apple at least has device management software, Enterprise solutions for app distribution (yes, without Apple controlling what you install), iOS offers ways of locking down, locating and wiping devices, the included email client works nicely with accounts with lots of folders, VPN of any kind is fully supported out of the box, you can rely on updates for years, you have just two models to chose from...
Face it, Google cares only for one thing: Eyeballs looking at the ads Google sells. Yes, Android is somewhat "open" and as a geek you can have lots of fun with it. But basically Android is a vehicle to beam ads at consumers and Google has everything revolving around that.
To employ iOS in the business you just need to look at things in a sober way. To employ Android you need to be a fanboi.
Things may (and probably will) change later on, but right now you need to be a kind of Android fanatic to coerce Android devices into corporate/business settings. And as usual with "everything is possible but hardly anything you need works out of the box" you need to take full responsibility and lots of time. With iOS you evaluate some products, look at the costs, make a decision and you're done with it. In any professional setting the latter is just the thing you want to do. It's work, not a hobby.
Sorry for injecting some realism into the discussion.
