Maybe I'm in the minority here, but the problem I see is that there is little pressure for computers to push technology forward.
I bought the iMac with Retina when it came out two years ago. I face two problems: one, what can't it do?, or what does it struggle to do?, and two what is there to replace it?
The computers we have today all greatly outpace what we can do with them. Intel has recognized this and the new processors that they are producing are by and large not more powerful, but more efficient.
So, I'm not giving Apple a pass on not introducing new Macs or lowering the price, but what can't you really do with your Mac that an Apple update is going to enable?
And if upgrading enables you, then you probably were rocking some old outdated crap, in which case it's your fault for not upgrading at the last refresh.
People who have an Apple Watch are disappointed with the marginal update of the new Watch. But since I didn't get one, the new one looks kind of good to me.
So, I wonder, as much as I would like a new machine announced that makes me want to buy it, what would that be? What will it have that my two-year-old iMac doesn't have? TB3? TB2 & USB 3.0 seems fast enough for what I do. More accurate color? I don't do professional photography.
What is it that you think these new machines will do that current models won't do, except be made up of more recent hardware?
