Since my email accounts are all Google, I prefer using email on the Note 2 over my iPad. I can store documents easier on my Note 2, and any Office app or email client can access those files. I can store document apps on my iPad, but they have to be done within the confines of that particular app. I can also receive an email from someone requesting a document I have stored on my device, attach the file, and reply back to the sender with the document they requested. I can't reply to an email and attach a document on iOS. I have to go to whatever app I have the file stored on, create a new message, then email it. Too many steps in my opinion, and if you don't have their contact into stored in your address book, it makes it that much harder.
