The advantage of any OEM remote is that it has all the buttons with the correct labels. We don't have the original Bluray remote around anymore, but it has many of the same buttons (including the A/B/C buttons), so this would be a good remote for that. The TV came with a Roku remote, which means it has very few buttons, but the TV itself supports many more.
So, all in all, if I were able to re-purpose the top 3 buttons (ie, OnDemand, Interactive and MyMultiview) to be STB/Blueray/TV device buttons, I could see the kids liking this remote. We never use the OnDemand, Interactive and MyMultiview functions, so we don't need those functions.
But, another reason is, just because we can.
