lifehack.org (main website link) posted an article on how they use online applications instead of desktop applications, the idea being that it doesn’t matter any more which operating system is running on your computer since you can have all your applications online including Office-type applications, backup, file management and so on.
I believe it’s an over-simplification, but the idea is appealing. I do think that we will have more of our applications online and maybe in the near future all our files will be online, but currently the desktop experience is still important to most users. Generally speaking, I adopt Jeff Atwood position in his post Are Web Interfaces “Good Enough”? (via Digg)
