Why do people even use gmail when there is Outlook.com? It's easier to look at, easier to use, and more secure. Oh and people only jumped to Chrome so quickly because back in the day it was basically forced down their throats by being included with every free download of anything and installed on many PC's without the users even knowing it. It's a good browser, definitely better than FireFox, but isn't all that. All it did was put Google in a market position to push out competing web technology companies, eg Adobe, to force upon everyone their own versions of the same stuff.
Sorry, not trying to rant, but Google is one of the worst companies every and things are just now coming to light proving this. Any company who deals in marketing and selling information... well you decide.
