With few exceptions, the reviews have been universally positive. They have had caveats regarding pro apps, but beyond that, you're imagining things.Got a link to some examples in particular?
Regarding IPP - Tech podcast after tech article that is actually going into detail about IPP is pretty disappointed with it. It's more about the fact they rushed it out with all KINDS of IOS interface issues and incomplete/unaddressed areas and then the lack of accessory availability.
Were you talking beyond IPP?
And exactly the sort of negativity the OP is talking about.
Not to mention, accessory availability has absolutely nothing to do with the quality of the iPad Pro, and will be all but forgotten in short order. In bringing it up, you show how weak your overall argument is.
