Yep, I've since tried Opera Mobile and it seems to work even worse.
Opera Mini takes me to the standard hotmail inbox. Opera Mobile only takes you to the mobile version of the inbox - so you can't even consider getting or sending attachments.

Httpmail no longer works unless you subscribe to hotmail plus, which I'm unwilling to do.
