"sometime int eh future, all our entertainment needs will come in ONE package, and i mean everything."
The problem with that idea is if something breaks you're f*cked. One thing goofs up and you suddenly have no PC, TV, DVD player, etc. Plus such a device makes it easy for someone to steal all of your electronics. They just have to grab one device. Finally if everything is in one machine then all of your electronics are made by the same company which is pretty restricting. I don't know about you but my CD player, DVD player, and PC are all made by different companies. Some companies are better at making different electronics so if you want the best DVD player and the best PC if everything is all-in-one you can't do that.
Realistically you for the most part can cover all of your electronic needs with a PC. It can function as DVD player, CD player, MP3 player, TV, radio, and it can play games. Yet there probably aren't too many people that use their PC, and ONLY their PC, for all of those functions. If all-in-one machines to some extent exist already why haven't they already become the standard? I don't think they're ever going to. If they were then everyone would have one of those VCR/DVD combos.
