It *is* misleading and it *is* a problem.
Imagine that you're a software developer slash information technology manager at a SMME and your boss announces his intention to go on a business trip to Durban the next day. Just as you're thinking, "Cool, an opportunity to actually do some work while the boss is away," he throws a curve ball: you must get his notebook to connect to the Internet, wirelessly, and do it *now* so that he won't miss any mail while he's away. You secretly wish for a little more time, but, being an uber-geek, you say "No problem," and jump on your bicycle to go buy him a PCMCIA Edge card and a Virgin Mobile SIM, complete with airtime, to do just that. When you get back to your office, you walk in the door with a smug look on your face imagining how impressed he'll be when all this comes together. You whip out the l33t-looking PCMCIA device, slot it into the PC and start opening that VM-starter-pack. Now you're really on your toes, so you pre-empt the need to put the SIM into a real phone to activate it before you put it into the PCMCIA device. Time for that bulleted list... bullet one is easy, no problems there, but after that, your stuffed. No calls, no SMSes, no data. Nothing. How the f**k were you supposed to know that it wouldn't work? Now, instead of giving the boss a working click-the-connect-button-and-surf solution, you have to try to explain to the boss how he's going to have to fight to get it working on his own.
That's not my idea of fun. I know. I've been there and done that.
Ok, I'll be fair - I don't know the first thing about cell phones. I only make calls on mine. Ironically, I don't do VCR's or DVD players either. Give me a PC, Windows, Mac, Linux or Unix and I'm happy!
