Don't be surprised if some of the earliest Ara phones easily fit within your budget.
Google’s Project Ara was something which we didn’t think would become a reality so easily and the move to bring highly customized phones to the mass market was also criticized a lot but the project still found enough strength to keep moving. However, the processors seemed to be posing quite some challenge for the project and it was Google’s top priority to get the processors to work with the technology. It is not every day that we think about taking the heart out of a device and easily swap it with something of our desire. But this can be made possible with the creation of a special CPU which has been designed specifically for this purpose.
For this purpose, Rockchip has already started its work and is currently developing a system-on-chip with modular tech built-in. This means that our phone is no longer going to need any bridge chips or other special tricks to let you switch processors in an instant. In order to see how it works, you will have to wait till next year because the Rockchip-based Ara prototype is going to arrive in 2015. The criticisms to the Ara project have died down slightly and we can see how Google has made possible the use of this plan which makes and the efforts have made Google's vision of a completely upgradable handset both feasible and potentially inexpensive.
