One misconception floating around about Nokia’s newly announced N1 tablet is that it’s running Google’s Android; however it’s not. The Nokia N1 is running Android Open Source Project, or AOSP for short. Although AOSP is relatively free of Google influence, Google do make their software release variants available to AOSP, supplying every line of their modified source code to the open source project. The Nokia N1 runs open source Android as well as the Google customizations brought in Android 5.0 Lollipop, meaning that it’s essentially lollipop based on AOSP.
Running AOSP means that the N1 will launch without Google play services (including the Google Play store), Android’s biggest weapon. Instead the OEM (NOKIA) will have to make their own app store and populate it with apps of their own. However the apps are usually fully compatible and require little to no modifications, so it’s simply a factor of getting the publisher to add them to another app store (and there’s no reason why they wouldn’t). Of course you can also gain access to the Play store and its apps by side-loading them onto the device, but that’s another story. Although i haven’t been able to find confirmation of which app-store the N1 will run, it’s possible they might re-purpose the Nokia store used on the Nokia X, but it’s not clear yet.
The biggest difference between running AOSP and Google’s Android (besides the Play store) is getting the Google related updates and feature fixes on the device, although Google are quite happy to supply the latest source codes for their builds; it still remains a matter of Google supplying it then having the manufacturer (Nokia) add it to their source code and push it to their devices. The advantage however is Nokia can freely preload their own mapping software HERE maps onto the devices,without being forced to bundle in Google maps onto the device.
It’s worth noting however that Nokia have confirmed that the N1 will be shipping with an unlocked boot-loader, making it a relatively simple process to flash newer versions of the software onto it should you be impatient for future updates.
