I agree - sometimes we forget that Apple caters to my mother and my nephew just as much as it does to us - this is a segment which still has growth potential (still plenty of elderly ladies out there without computers; and new teenagers produced all the time). For these types of people Apple is just fine.
I think though what many of us are complaining about is that "Pro" used to mean a machine that was targeted at us, i.e. Professionals. I guess now it just means "high end" but I remember a few years ago the Macbook Air was targeted at the "pretty things" market.
I remember about 5 years ago my brother a professional animator complaining about how Apple dumbed down Final Cut Pro X to the point it wasn't usable in his domain. These days his shop doesn't use Macs any more (typically a staple industry).
I've a friend too, who works in automotive industrial design who won't touch a mac because it just doesn't have the power he needs.
My sister is a professional photographer and up until a few months ago I wouldn't have hesitated to recommend her a MBP but in all conscience nowadays I can not. This dilemma actually forced me to look at Windows laptops and I'm amazed how much they've come along in the last while.
So it's not just "us" that feel abandoned by Apple, but professionals from other walks of life. It's fair enough, if its a segment that doesn't make as much money for Apple as it used to, and as a business they have to make business decisions.
As professionals we have to make these decisions too, and if Apple isn't the right tool for the job we need to source one that is. But, there was a few years there where it felt like Apple was our friend. They made some amazingly pro-friendly gear. It seems those days are waning, and that relationship is coming to an end, and some of us feel a little jilted.
On the one hand, we hope that this "friend" will hear our protests and change their ways but we know deep down that won't happen. On the other we have to give the best advice to our friends and acquaintances as to what is a good device for them. We, as in "those sorts of groups" have a responsibility to critically evaluate new hardware in this light.
