@Vamp898 They are also unusual for putting DRM in their camera so, if you install AOSP (which you have to build yourself), you automatically lose any hope of taking decent shots and recordings.
I know how huge Sony is and where they work, I still think that once you publically ship something, it stops being fully yours - everyone who wants and pays has a copy of the implementation of those ideas, which they have the right to look at and modify. It's all artificial barriers (DRM, legal) on top.
