You can live without a desktop computer:
As long as you don't type a lot, and can do without a real keyboard
Not everyone needs to type a lot. This is why my Facebook feed is filled with idiots who use OMG and LOL and 'u' instead of 'you'
As long as you don't mind scrolling more
Tablets are actually pretty good for browsing. The scrolling is very intuitive and even 'fun'
As long as you don't need to print anything
You can hook up a tablet to a printer via wi-fi
As long as you don't need to read or burn a DVD
DVDs have gone the way of the Dodo. This is why the Macbook Air doesn't have an optical drive.
Funny thing, the DVD drive on my computer stopped working because I hadn't used it even once in the past 2 years. I haven't really missed it.
As long as you don't need to plug external hardware like a scanner or an overhead projector
This relates to a very small group of people. Even then, I'm sure there are wireless solutions to this problem.
As long as you don't play games
Not everyone wants to play Skyrim. Most people are perfectly happy with Angry Birds
As long as you don't use CPU-intensive applications
THIS is exactly where computers will be sorely needed. For anything that requires involvement, computers are still the way to go.
The way I see it, for the average consumer (this doesn't include people like you and I who work online), desktops will be something to be used only when writing research papers, doing some hard-core video editing, etc. For everyday consumption, tablets are more than up to the task.
But now one desktop PC in the household can be enough when there used to be two or three.
IMO desktop will remain popular in corporate environments.[/QUOTE]
