My back of the envelope calculations, so I may be off by an order of
magnitude, is that in memory a 41mp image, will take up 230MB plus,
before you start manipulating it, (a 16mp image takes up about 90MB, I
didn't work out 24mp, I don't have that camera).
I've got a fairly recent computer, my old faithful PC finally fried it's
CPU about 6 months ago, and I built what I consider a sweet spot
machine. Maximum capabilities for minimum price.
For example it's got 6 cores as opposed to 8, going from 1 to 2 to 4 to
6 cores added between $10-$20 dollars for each increment, going to 8
almost doubled the price of the entire system. I specced the whole
system that way. I'm pretty sure that I'd have to do another upgrade for
to handle 41mp files.
Right now if I'm interested in prints I can make 13x19" prints using a
16mp camera, that are better than anything I could do with 35mm film, or
for that matter Medium format in the past, and I can go bigger, into
print sizes where only Medium format didn't fear to tread. If you're
planning on a slide show 16mp is higher resolution than a 4K display.
Sure it's always better to have more resolution for cropping and image
manipulation, but you reach a point of diminishing returns. Except for
very specialized purposes very high resolution systems are overkill.
Hell if all you ever do is display you images on the internet, then 6mp
is overkill.
I'd rather have a 24-36mp FF sensor with better high ISO response and
faster frame rate than a 41mp sensor with about the K-3's ISO response
and slower frame rate.
Oh, and yes I'd like the aperture simulator back...

What is it with outrageous Pixel counts?
A 42 MP full-frame sensor has a pixel size that's intermediate between
the K-5 and K-3. Why do you think it's outrageous?
I think he's referring to the total number of pixels, not the pixel
density.
