Will the DVD be replaced by memory sticks soon? Will I have to replace all my DVDs with memory sticks, like I had to replace all my VCR tapes with DVDs?

I hate to break it to you, but Aux Arcs is right... Storing content like music or movies on an actual disk is so last year, the future will be all about better and more easily accessible cloud computing, which allows us to stream movies and other content stored in millions of servers all around the world, rather than in a fragile, scratchable disc whirring around inside a dvd player.
