I doubt you are a professional using the ipad, but anyway, I agree with TechNerd, the ipad should have been in 2 versions, ipad for the kids, and ipad pro for the professionals, with ports, SD card slots, upgrade ready in terms of internal memory, a bit more modular...
What is not in dispute is that Apple did their very best to NOT innovate, the ipad is a joke now, $1700 to over $2000 for the 2TB 16GB RAM 12 inch is insane, no way it is over $100 for apple to produce, if apple sold the 12 inch 16GB RAM 2TB model, with SD card slot and dongle in the box, for $499, they would not take a loss, it would sell in the millions of units, folks would buy plenty..The idea of sell more for less, or sell fewer items for more??? I don't know.
The ipad has not had any development in a decade, it is the same as it was in 2013, zero innovation occurs at Apple, none, all we will see tomorrow is promises and garbage.. Stuff that will tank, like that stupid bluetooth speaker and the round mac pro that was just hopeless... Apple are not trying...
Apple gave up on the ipad after generation 2, that is very obvious, as it has not changed in basic function, it has the same faults as generation 1, and a broken OS... really.. The pro version is not professional standard... however you define that standard...
There is no reason Apple cannot take a bath on the ipad, all companies loose on certain ranges, costco does this on chickens and hot dogs, lossleaders, products you use to get customers into the store, what you loose on hotdogs you gain in toilet paper or pumpkin pies... Apple could triple profit in the selling of add ons, at $499 I would buy 2 ipads... at $2000 none...
