You don't want to run your own mail/web server. At least, you do not want a lot of people doing it. Because most of the will get the security part wrong. Horribly wrong.

Well, some ISPs have in their contracts a free custom mail and webserver for every customer (for example, mine does).

This obviously diversifies the options quite a bit.

Having my email or webserver tied to my ISP seems terrible. What happens if I want to switch?

That's the way it always used to be - for example, many americans still pay a small fee to AOL.

But you can just move it to any other hoster.

Apple Maps has also become a serious competitor. Apple is still playing catch-up in some ways but every year they keep closing the gap further. Almost every 'catch up' feature they have added is as good or better than Google's implementation. In the same time period Google Maps hasn't improved much and has taken some steps backwards in UI.
