MS don't need to be jealous, I'm no particular fan of Windows but I know that all the billion dollar corporations running the world/government whatever, sure as hell aren't doing it on an iOS device. As other posters have mentioned, Apple are a consumer market company, loads of grazing - but other than your social media tweets and status updates no actual work is being done on them right? (ok, before I get flamed off the boards, some exec on an iPad is probably approving an email on a big deal - but I bet the tender wasn't created on an iPad/phone)
