People are funny. For example, we invent, produce, and replace devices purely for the purpose of making our lives easier. Then, realizing we have so little to do that we're out of shape, we buy gym memberships. To top it off and make the situation even more ironic, many of us drive to gym in order to get fit!
It's the same on many fronts, even in Electronics. I just finished printing up some materials for my classes. I don't print on a daily basis though. In fact, sometimes weeks pass without me needing to make physical copies of any document.
I know that a wireless printer would be convenient, but honestly I welcome the exercise involved in lifting my Brother printer from its storage place in the bedroom and carrying it to my computer. The process takes approximately thirty seconds. Why should I buy a printer with wireless capabilities?
