Microsoft Mobile!, ah! what a joke! lol
Anyway....more like 10 years...it's enviable technology is going to get small/lighter/energy efficient and more powerful but that would include the desktop PC in one field or another!.
The way people are using this technology is changing and Mr and Mrs consumer won't be popping in to the large electrical store and walking away with a complete Desktop PC anymore, why would you?! if the technology allows you to carryout your needs whiles sat on the toilet, for example.
Doesn't mean there no future for the Desktop PC, they are used in all multitude of situations which also include gaming!.. all depends on what you want from it which a Desktop gives you, choice!.
In 5 years 'watches' are as powerful as my Desktop PC....imagine how POWERFUL that current desktop would be! lol
Hmm..I don't think anyone that's replied has stated this, only you my friend!
It's just declining on the common budget consumer market!...we can't change that, but to think it's obsolete
would be crazy!
