Why do computer manufacturers make so many different models?

The reason that computer manufacturers make so many different models is that everybody wants something different. Some people want a gaming laptop, some people want a cheap computer, some people want a portable netbook, and everybody wants something different. Let’s say that a computer manufacturer made just three models of computers, they would only appeal to a small range of customers. By making many models, computer manufacturers try to appeal to as many people as possible. I don’t believe that any computer manufacturer would even try to make few models of computers because they are smart enough to know that it would not be profitable and would lead to their destruction. And anyways, it doesn’t affect the end customer, so why does it really matter?

Are wearable computers in our future?

In my opinion; no, and I don’t think that they ever will be. This is for many reasons. First of all, the screen size would have to be very small for it to be viable, at the most four inches. The small screen size would make it not realistic to have it as a primary computer, because a four inch screen won’t give you very much productivity. Imagine trying to browse the non-mobile version of a website on a four inch screen, impossible! Also, a wearable computer would be bulky, get hot, and it would be too small, that is the main issue. Also, smartphones are pretty much wearable computers which you keep in your pocket, and who really needs a computer attached to them anyway? People don’t want to carry extra devices, they want everything in one device. That is why even if wearable computers are someday introduced to the market, people will not buy them. People will just continue to use their smartphones, which will continue to get even more like computers than they already are.
