In the first iteration of any technology, it's amazing that you can do it. When the first Motorola mobile phone hit the market, it seemed miraculous to make phone calls unconnceted to the grid; only later did it become clear how unwieldy that first phone was.
The same is true for PCs. Early "portable" computers would make you laugh, because of their size (large), price tag (high), capabilities (poor), or some combination of the three. But as you take this tour through the history of mobile computing, we urge you to remember the day when it was amazing that you could lug these things around at all.
