'On the way to the cloud'
Presumably a cloudy future where literally everything everyone does is owned, controlled, processed and analysed by Google, by any chance? Gee thanks. Or you could interoperate this as a way to make Chromebooks marginally more useful and saleable, particularly to businesses that don't want to (or can't) drop dependence on MS Office and 'other legacy apps'.
There could potentially be some longer term performance benefits however... MS and Google has been pushing more and more use of browser based office applications, but as far as I'm aware they still process data (slowly and inefficiently) on the local client. You just can't open a stonkingly massive and complex Excel model in the online application. But if the file is already in the cloud (via Drive, One-Drive or SharePoint etc.) and the software interface is already in the browser, why not use much more massive cloud processing power behind the scenes, to deliver something more capable than the local hardware or native application? That seems to be the missing link, unless I'm misunderstanding something?
