I would be interested to know that has there been any discussion about Omnigroup developing web platform? My personal use for this would be the fact that I have to use PC's in my work environment. I doubt omnigroup is developing a windows app, but web platform would be a good solution for PC users.

Also lots of GTD apps are beginning to be based on web (Wunderlist, Getflow, Baseamp), so if Omnigroup doesn't develop something like that they might be left behind the current trend.
