I have an Inspire 1 which I now hardly ever use because it's so much easier to carry around my P3P in my backpack and the photo quality of my P3P is just as good as the Inspire. I was thinking of selling my Inspire and possibly the P3P and getting a P4 instead. Just two questions , is the photo and video quality much improved on the P4 over the P3P and lastly are the dimensions the same as the P3 so I could fit it in the same backpack ? cheers. BTW this is the backpack I have for the P3 and it's great !
