Wikoogle: I'm a 50 something photographer (wishing he was on the verge of retirement
) ... and I teach a photography course at a commercial photography college. What I see is that 80%-plus of the students are toting Mac notebooks around, and 90%-plus wouldn't know the tech specs of their machines if their lives depended on it.
Yes, they know about cameras, though not always how to use them (but then that's why I have a job). Some of them can do things with Photoshop that would make your eyes drool. But for the most part they could care less about the specs of their systems, beyond the basics. Does it have adequate RAM, HD, and processing speed. Does it Youtube?
And, if you think students are not a valid sample group, I also hang out with a couple dozen pro shooters - a number of whom work and sell internationally - and for the most part, they also don't spend a lot of time worrying about the tech specs of their systems. This group knows more about cameras, lenses, sensors, and printers than you could imagine was possible. But, other than at the time of purchase, they don't really care about the tech specs of their systems. And at the time of purchase, its a case of buying the best system they can for the amount they have budgeted. As a fine art photographer, I actually know much less about camera specs than they do.... but since my hobby is computers, I know much more about systems than they do. And I don't know a lot.
Like most pros, they rate "Best" as 1) Being reliable, then 2) Making their workflow faster and efficient, and finally 3) Being able to continue using their software investment. No body I know cares about fast boot times. They want to know if they can transfer 15Gb of files from their external HD faster. They want to be able to apply a colour correction to 155 images in Lightroom, and not have to go for tea while it processes.
And yes, most these photographers are what you disparagingly called "close to retirement". One of them is in fact retired. Of course, before he retired he was in charge of transitioning the darkroom of a major city's two daily newspapers from film to digital. When he was done Pacific Press was the first publisher in North America to be fully digital. He doesn't care about tech specs on his computer..... but oh boy, does he know about cameras!
