I’ve been playing around with JoliCloud as I think it is a possible solution for the desktop in the cloud, accessible from all my machines. I like the integration with DropBox and Google Docs but the rest currently seems like a simple bookmarking system. I like your description of it as a speed-dial page – that actually makes me like it a bit more!
The first thing I’d like to see added is a way to manage all the apps that get added to the dashboard. They need to be grouped in some user-defined way, such as productivity or photo, so they make more sense. Then I’d really like to see some form of widget icons, telling me the weather, or how many unread gmails I had. Wouldn’t that be fantastic?!
It’s definitely got potential.
