Kinda like when VCR's first came out. Beta was first, then came VHS. Everybody was thrilled and bought their favorite movies. Then came DVD's and people found out that they had to buy their favorite movies all over again. Now BlueRay...gotta buy them again, and to hit the market by 2015, TV's with movies on memory sticks. The TV will have a small SD slot and thats how you will watch your movies, or you can buy a card reader and connect it to your TV.
So whats my point? Give up trying to keep up with technology. You'll go broke doing trying to do so.
