The only upcoming Google product that I'm really excited for is revolutionary in a very different way. Smartphones, tablets and many all-in-one PCs have one major flaw: You can't upgrade them.
I've been following Google's Project Ara since it was originally announced, because it might just change everything. Instead of just buying a smartphone, you'll actually be able to build your own smartphone, Lego-style.
A Project Ara phone buyer will first have to buy an endoskeleton or "spine." Project Ara endoskeletons serve as the phone's foundation and come in mini, medium and large sizes.
The size of a Project Ara phone's spine is important because users can easily buy and insert any hardware they want.
