Portability of an object may mean a lot nowadays. The more compact and the more portable an item is, the more likely will it be chosen by consumers in the market. As the world starts to integrate into one economic unit, we can see that people are moving and migrating from place to place at unprecedented rates, which may well be the reason why they go for portables.
An object's portability has its drawbacks, naturally. The most obvious among these drawbacks is its relative weakness compared to their larger counterparts. We can see it in a lot of items--computers, game stations, televisions sets, and even mini staplers--that it is always a struggle between portable and power. Between two products of the same generation, the non-portable is usually the more powerful. This is obviously because of the fact that portables have less capacities hardware-wise (which results to lighter weight).
It is also a matter of price. Portables, for all their weaker capacities, are sometimes much more expensive. There are portables that are extravagantly priced, such as the Macbook Air, while some others are cheaper yet expensive.
Ah well, every convenience that we get has a price. As long as consumers find the price right, and the features adequate, they will continue to purchase these portables and portables will continue to flood the market.
Now I am waiting for a car that can be carried around inside a briefcase. Do you happen to know where I can find one?
