If you think those things are difficult, then you've swallowed the FUD without bothering to investigate the truth. Do you seriously think you CAN'T have multiple chargers??? Why? Who is stopping you? Who is stopping you from running ANYTHING unattended for several months? Not Apple. Apple Mac OSX is UNIX, one of the most bullet proof operating systems around and most of mine run months at a time without restarting. What's your problem??? I have one that has run for two years without a restart. . . Unattended. You guys just really don't know what you are talking about. You spout myths, thinking they are true. We who DO know shake our heads in wonder at the nonsense that spills out of your mouths.
Of course you can have multiple Apple chargers, as long as you're willing to mortgage your house to pay for them. I'm talking about chargers so cheap that you can buy a dozen and leave them around various places so they're available IF you might need them.
A classic example is our console stereo. It has an Apple iPhone docking station. It's quite handy, you can charge the phone, and play iTunes through the stereo. Except.....my wife switched to an Apple iPhone 5. The wizards of Cupertino decided to totally change the hardware format of the dock and the console stereo is now useless for her. And it cost more than the iPhone.
Indeed.
