Ed put on a great presentation and for the first time the penny dropped on what IBM has been talking about with the social mail client.
He demoed the client and it looked great. No longer will the backend mail server matter.
The devil is always in the detail, but if IBM can ship this (and I'm sure they can) with support for Domino/Exchange/Google etc I think we've got a winner on our hands.
For the first time in a year I clearly understand what IBM has been talking about.
