Again I will say give me a source that says the numbers.
I have seen a number of credible sources that say otherwise- that there isn't a huge savings between the two forms of media.
You are a guy on the internet that keeps basically saying trust me I know stuff.
P.S. Also from Wired, but in April of 2009:
"For publishers, the majority of a book’s costs is not in the printing or shipping, says Savikas. It’s in sales, marketing, product development and editorial. "Its more about the fixed costs," he says."
Depends on the user. I replaced the hard drive once and LCD twice, in the last year, for the same user. Also did 3 virus removals, one of which required O/S reload. I see her notebook again, on a co-worker's desk right now, for a main board replacement. The bottom plate of the notebook looks like it's been cooked. Literally.
I generally see the same client, 3 or 4 times a year, for something. Call it 0.5 times (on average) for some hardware related issue. My group oversees roughly 2500 computers.
And then there are people like me, who think that books are a sacred thing and try to take good care of them. I've never lost a book, though I've worn a few out.
I managed the communications infrastructure for a 15-site (CA to NY to FL) company for a decade. I think your experience is anomolous. Or you should reconsider your vendor. And/or your policies. Or, more likely, you are citing anomlies yourself and you have hundreds of clients who do not need that level of attention. Blame that woman you are speaking of, not the tech.
