You sound a bit too worked up over this. Perhaps you're a Microsoft employee who's sick of Google getting all the attention. I've been using gmail since it first came out and am completely satisfied with it. I also use Outlook to back up my Google mail. I don't care that Google scans my e-mail. It's automatic. No human is reading my mail besides me. (Well, besides me and some government agencies.) Google has to get payed somehow to keep this service around. I like the instant searches. I like that I can get to my mail from any device, any browser, and from anywhere. I like how reliable it's been for me. I like all the storage I get for free.
I'm partial to Google for most everything: mail, calendar, documents, searches, etc. I also use Windows and Office when I have to--I personally payed for them. I have no idea what wonderous things Outlook could do for me that gmail doesn't. Since I can't think of anything more I want it to do, I'm not switching to Outlook or anything else for my personal needs.
I don't know anyone who uses Outlook for their personal mail. I work for a large software company. None of my colleagues use Outlook. We use Thunderbird.
My two cents.
