"Or for suggesting that $3/month is a good deal when gmail does it for free?"
They said three quid, not dollars, USAian. And yes, ad-free with IMAP support is well worth a few quid a month to some people. Others balk at three pounds a month for it because it's not worth it. But it's nice to be able to use your own local client, or easily use digital signatures (which we all should be doing) or have it come from your own domain name (which you can do with the paid version).
Not everyone wants the same thing and to a lot of people, £3 a month is well worth anything that makes things more convenient. And many of us prefer to pay for something with cash rather than with privacy too. It's all personal choice, but as predicted, downvotes have come just for saying what I like and for suggesting someone get a free trial and make their own minds up... Someone asked a genuine question and I answered it. My point about how you can be downvoted here for liking a Microsoft product has been amply demonstrated too.
