Both IFA 2015 and Apple's large keynote event are over. While the new iPad Pro, Apple TV, and iPhone 6s are still starting to sink in, the mobile world is ready to move on to the next big thing: Google's new Nexus smartphones. We've already seen leaks of LG's version of the device but now we're getting a slightly different deviation. A black Nexus 5. That, however, might not be the most notable part of this leak, which is the remote possibility that it will only have 2 GB of RAM.
