Can you imagine that tablets will be the future PC?
Tablet computers like iPad are popular today because they are much more portable and fashionable, and one day their functions may be powerful enough to replace the current PC.
I mean can you imagine that you will not see mouse or physical keyboard any more, only tablets' touch screen? Then that will be a completely different world.
You can see that mouse can be omitted in current tablets, but what if there is a way that makes typing with touch screen as fast as typing with keyboard?
