How long did it take for you to receive the said 4 gigs by mail? What was the throughput in kbps? Would you be happy with internet connection that had similar download times?

Simple changes require simple training. It doesn't always have to be 5 days workshop and in many cases it doesn't need to be done in person for every users.

Most simple form of training is informing the users about the changes. Way too often we think that users should be able to pick the changes on the fly and there is no reason to "train" the users; they should be smart enough.

I consider myself to be fairly competent when it comes to IT and am absolutely sure that I could figure out any changes thrown at me, but quite often I don't want to. I mean, why should I figure all the changes as I use the system and spend hours and hours of cumulative time trying to understand what has changed and how? More often than not, that would be waste of time. Quick 30min or 1 hour training could easily save hours for the people who would otherwise figure out the changes on their own. I find that pretty counter productive.

I'd suggest that everybody makes training as part of the change management process. One of the key things to remember is to keep it simple so that it doesn't waste everybody's time. Smart users need less training. If the guy in warehouse uses computer once a week, then the training needs to be completely different level. If you perform a simple change then training doesn't need to be all that complex, either.

How is it GP's fault that lawyers don't want jurors that want to be impartial and would consider all the evidence?

I'm sure that's a mutual feeling.

OP was working in management, not as techie. One of the key tasks of IT management is to be on the same page with rest of the management team. It's their job to make sure that everybody understands the ideas proposed by the IT department. Way too often techies come up with excellent ideas which they can't pitch to the business side.

In the same way as marketing staff doesn't really "get" IT, IT staff doesn't understand what's going on in marketing. Both sides probably see each other as completely irrational and defying logic.

IT management needs to be able to argue their point clearly so that the intended audience can understand it and escalate the problems, if needed.

No, that's hard-core capitalism - supply and demand; all that jazz. Apple doesn't see any value in his product (exploit) so they aren't willing to pay. Somebody else could be willing to pay for what he has so he could sell it to them instead.

Normally when there is much more supply than demand then manufacturer needs to start advertising to make sure that the potential buyers are aware that product exists. When there is more demand but almost no supply, then potential buyers will advertise to every potential manufacturer (or author in this case) that they are willing to pay for certain product, if anybody has it.

Entry barrier to computing has gone down, a lot, in past 10 years. Also like you said back then most of the disks were shipped unformatted thus most of the people knew they'd need to format them before use.

Nowadays flash drives are predominantly shipped formatted so people assume that they work once you plug them in. If they don't, people assume that they are broken.

One option is to move the write protection tab to 'LOCK' when card is full. Only move it back to 'WRITE' when you transfer the data to PC and clear the card.
