Q u o t e: We're going to become even more dependant on online services to be able to use a computer. If that's the direction that all software's gonna be in the future then I can already see my computers being just bricks in my home and unable to do nothing on them should any of the 'external factors, acts of god' and crap like that start affecting me.
...You need not depend on proprietary software as there will always be open alternatives that don't put you at the whim of some company's wrath. Although this may prevent you from playing AAA games and such, your computer will hardly become a brick incapable of doing anything whatsoever...
