Project Ara is surely one of the most exciting things Google is working on right now -- at least from the ones we're aware of. Better yet, given how young it is, chances are it will only keep getting better and more interesting. While speaking at a Purdue University event, Google's Paul Eremenko, director of Project Ara, recently revealed that the company will be taking a cue from the Play store to create a similar shopping experience for its modular smartphone. What this means, essentially, is you'd be able to buy or sell different components from a single hub, just as is the case now with apps, music, books and more on Google Play -- and it would also include reviews and recommendations. Eremenko didn't mention any details related to the status of Project Ara, but you can check out the full talk after the break.
