All technology has a certain lifespan. Desktop computers may be reaching the end of theirs. Laptop computers are now as fast and powerful as any top of the line desktop. Importantly,laptops are becoming cheaper and cheaper. Desktops have lost their power supremacy and are now losing their cost advantage as well. So how many more years do you think desktops will really be around?
Desktops haven’t really lost their power advantage, it’s just that it’s less noticeable in day to day use.
Desktops are upgradeable and have a wider range of peripherals, most laptops have limited upgradability. Desktops also have powerful graphics cards which are more suitable for gaming than laptops, even those that have separate graphics.
Desktops are also less stealable than laptops and have less overheating problems, so some corporates are likely to stick to them for a while.
There is also a trend for computers in which the current latest, most powerful hardware cannot ever currently fit into a laptop. Once the miniaturization is cracked, it moves to laptops.
But perhaps the most important reason that desktops won’t be made obsolete by laptops is that they will probably both be made obsolete by a combinations of pervasive web access, virtual computing and improved access devices.
