With the gmail web interface I already have all of these features, actionsteps are stars in gmail, i use yellow & red bang, and red star .. just press s to rotate, attachments have never been an issue but maybe thats just me, searching for "from:a@b has:att<down><tab>" is quite quick enough and using filters & labels gives me the notification functionality, e.g. messages from facebook get a label, i can see facebook (3) or whatever on the left, but it will work for any type of email i wish. "meh" is my main reaction to this, unless it has something new and is as transparent to synchronisation across devices as gmail i won't be interested
