Leave email alone. It's doing it's job 95% alright. Just use a reasonable client (e.g. http://mail.google.com, Sparrow) and there is really almost nothing to complain about.

The problem is that we are using email for everything. Since Facebook, people rarely send pictures to each other anymore. Since Blogging, people rarely send long personal stories to 100 friends. Etc', etc... Slowly and carefully we find the right alternatives to the default, which is email.

If you need task management, use Asana or something. It's really good, and it integrates with email quite well. Also, Trello is excellent as a flexible Kanban board.

It's all about finding and using (rigorously) the right tool. Don't force everything you need in computing into email, and you won't have to reinvent email.

I really doubt email will change at all. Maybe it will die, or be less common. But it will not change.

It's so simple, why change it anyway?
