Dell, from the computer owner's perspective, does some negative things as well.
Did you know that if you buy a Dell computer, you can't sell it without Dell's permission? If Dell finds out you sold your computer, they will blacklist you, and not sell you any more new computers! I know this from personal experience (I have been blacklisted for many years).
Much of Dell's hardware is non-standard, so that if you need to replace a major component, such as a motherboard, for example, you have to buy it from Dell because a standard board won't fit the case. Nice, Dell, way to piss people off!
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
