Ok. Easier to build for? In a business environment that's running all Windows servers and workstations? I don't know any small or medium sized businesses that employ iOS devs in-house...

You need Macs to build iOS software. Meanwhile, you can find Visual Studio already being employed in most business IT shops to build custom desktop and web software. I can't remember the last time I saw a job ad for an iOS developer that wasn't for a one-off gig or a mobile apps shop (or a marketing agency).
