That right there (what I bolded) is the reason why Apple does things like that. They know that they can get away with it.some people seem to foam at the mouth at the prospect that something that is good enough for them isn't good enough for everyone.
my entire computing life i've had to listen to people tell me what is 'good enough' ram. i've been heavily into digital art, digital video, 3d rendering and hell even computer science, since the early 90s. i've dealt with the "nobody needs that much" folks for literally decades now. heck, even check my post history when snow leopard launched and some sort of early compatibility bug with adobe after effects was causing a massive memory leak. i had bloody screen shots of my system monitor becoming totally ram starved and the entire system grinding to a halt, and there were still people on here who just said "OS X has great ram management, you're imagining it."
an 8mp camera is "plenty" for the "everyday use". the speaker in my iPad 3 is "good enough" for the "average user" the bazillion existing bluetooth keyboard accessories for iPads are "fine." for me, ram would have been a more worthwhile addition than ANY of those things. ram limitations might mean smaller drawing canvases. fewer video filters. any forthcoming productivity enhancements that are tied to a specific amount of ram in a device (e.g. air 2 multitasking)
that said, i'm still likely going to get the 9.7 pro. i want the drawing experience, and life's too short to wait for the 'perfect device.' but i'm a realist that it has limitations, and might have future disappointments.
P.S. If you are in the U.S. and are ready to buy, this week only the 12.9 iPP is only $50 more than the 9.7 Pro. (ends today)
