Changing technology

I've been using computers in some fashion or another since the early 1980's. I remember being introduced to the "power" of computers by the S-1 of the battalion in which I served, when she brought in her IBM "personal" computer, and demonstrated how she could manage some of the data she utilized (like awards, promotions, etc) on her machine. I was hooked. Later, the S-3 did the same, as did a company commander. The latter had one of the first Macintosh computers made, and when I saw it, I knew Apple was for me. It still is today, but what I can do now makes what we did back in the 1980s seem stone-age in comparision. The sad thing about all of this, is that technology changes so fast these days, that what you buy now, will be obsolete in a very short time. I keep telling myself that computers can't do much more than what I want them to do now; but then, some company unveils a new technology that makes me think otherwise. Sadder is that fact this all raises the balance on my credit card!
