I would like to see Nokia investing on some serious email client. Unlike the push mail ones, and the Nokia Messaging way (store and forward), a standalone email client would make some real sense.
Esp in corporate (though some have their own push-mail servers), it is not allowed to let some server receive mails for you and forward it to the mobile, whatever the prospects the later might have.
The built in email client is supposed to do this, but is not very efficient. Most of the screen space is occupied by the big buttons to delete and fwd mail. Comparing with profilmail, which doesn't do anything too great except render the basic view correctly.
It would be great to see if one can use the dedicated music button on 5800XM, to be context sensitive toolbar.
