NORMAN — I do not trust computers.
Let me rephrase that; I trust computers, but only to do one thing: fail. Computers of all types, whether desktop, laptop, iPhone, tablet, PC, Mac, Android, iPad, cellphone or TV (yes, Virginia, most modern televisions are computers), are imperfect devices, built by imperfect people in an imperfect world, and they all, somehow, some day, some way, will fail.
Another seemingly immutable law of the universe is that computers always fail at the wrong time; that is, they fail right as we are trying to get something done.
This makes sense, as we never use our computers unless we are trying to do something, and that is when they fail. Right as you are trying to send an important email, or finish a tax return, or print your homework, or process the company payroll, or watch that funny YouTube video, that's when your computer will roll over and give up.
When the inevitable happens, and your computer lets you down, what will you do? Will you have to close the doors of your business until your computer is fixed? Will you have to beg for more time to turn in your homework? Will you have to tell the IRS that your computer ate your tax return?
The solution to these problems is simple: you need another computer. As dependent as we are in this day and age on computers and our connection to the Internet, it makes sense to own at least two computers.
When one computer goes down, you simply fire up another one and get back to work. If you value your time and your ability to interface with the rest of the world, you need another computer to use while your "main" computer is being repaired.
I know some folks will ignore this advice, because they will think, "Oh, I'll just take my computer to Dave and he'll fix it lickity-split, no problem." I'm fast at what I do, but what if it can't be fixed "lickity-split?"
