Wow. Google deprecating Chrome apps will hurt the Chromebook ecosystem, who will develop apps that can only be run on a Chromebook? What's up their sleeve here? Expanding the Play store to desktops?
Chrome OS is actually not losing access to these apps for ~a year during which time the Play Store will continue rolling out alongside it.
What will be really interesting is when they roll out the Play Store for the rest of Chrome...
I imagine they are thinking that developers will make quick and dirty Android ports to Chrome OS like they did with tablets.
