But, there are some problems to consider here. Because apps exist in the browser, there will be no inherently common GUI to Chrome like we're used to with traditional OSes. The way we open documents, the keyboard shortcuts, the look of the windows and tools could wildly from application to application. What's more, your data will be scattered all over the place. In a traditional OS, I have my pictures folder, my music folder and my documents folder, and I can use whatever application I wish to open these files. On Chrome, I'll presumably only have access to documents specific to each app. So, if I'm creating, say, a birthday invitation in Google Docs, how am I meant to insert a photo that's managed by the Photoshop web app?
