Used to have 2 (old one, and pop out), now it has 2 (new one and pop out). (there is also the look for reply, and for chatting (which i use even if other is offline sometimes instead of a quick email), and the ability to revert to the old look)

By this logic, the old one is at least as fascist. Additionally, while you might not like the new style, "real" feature was removed, but the ability to write multiple emails at once, or write one while one is open, were added.

Edit: I just tried to old one to see it again. It is rather bulky. It needed a UI update of some kind at least. (which may have been accomplished not semi-popped out, i guess)

Technically, you still have two compose interfaces, but they have promised to remove the oldest one. To get the old interface, click the little downward pointing arrow and select "Temporarily switch back to old compose".

To be fair, you didn't choose the old one either. Since, ya know, it was the only choice.
