Except it is. Doesn't matter that there are more multiplats, there are still exclusives, therefore they have different librarys, fact. May not be a significant difference to you, but to others it is.

so the differences are the exclusives. ok, i can accept that, and if you read the OP, i fully acknowledge that and say that is a meaningful difference. is there anything besides that? 

The rest of what mummel said, hardware, features, controls, design, philosophy, etc.
