Both can be forced to follow corporate policies.
Both can connect to Exchange - and I mean a full connection, syncing email, calendar and contacts - without having to buy extra software or hardware
Come again?? Since when can you force Android or IOS to use corporate policies like locking down the camera, disabling instant messaging, preventing any apps from (apart from those you allow) being installed.?
No they can't both fully connect to exchange without buying additional software. Specifically Notes and Tasks DO NOT sync without additional help, and if you are runnning pre 2007 exchange, it's even more of a pain.
