I have a bunch of accounts there, since I game and want different accounts for different games or sometimes several accounts on the same game. Also it helps me be anonymous on the web since it's harder to track you when you spray yourself all over the web using different email accounts. I use Tbird to roll them all up and GMX works great with Tbird. And I use GMX with the web too. Very nice clean interface. And unlike Google, they support multiple accounts very nicely via web or clients like Tbird.
They have drive services too, but I've not used those much. But some. They work fine.
Give 'em a try. "Disclaimer: I am not affiliated with GMX in any way. Just a happy user."
