That's exactly the problem. In other threads, we've been discussing if the manufacturers will be motivated enough to put their special add-ons up on the Play store for use on the Nexus Experience versions. If they do this, not only does that give the Nexus buyer the ability to, say, get air gestures or their camera app, but since it would come in through the Play store it, too
, could be updated without carrier intervention or delay.
Put simply, a Nexus Experience device where all the manufacturer add-ons can be available via the Play store gives the best of both worlds and is, potentially, superior to either.
If the carriers don't do this, it is confusing the the average consumer. (For now, average consumers aren't buying via the Play store.) And, for me, I think twice about it. I don't want the crapware, but I do like some
of what HTC and Samsung are doing. My "thinking twice" is also partly why I want to see what the Moto X will be first. (Not counting any devices I need for testing on, of course.)
