There was a time when applications was moving from computer desktops to the web and was made such services like Ajax Word and Excel. But now looks like evolution is made the circle and applications from web is crawling back to computers to be like clickable icons again.
Desktopize in fact is very similar to Apollo and promises to let users access to web applications straight from their desktop and it looks like this kind of services is getting ready for action.
My personal view is that it is next step for applications, because making the circle from desktop to Internet and again back the applications is reached point when they can be used more rational and with bigger benefit for users. I think that next year will bring a lot of good news in this area and the biggest winner of this will be user.
