small improvements? SMALL IMPROVEMENTS?
I own a stack of DVD's that can hold 4.7gb. I also own several rewritable 25gb bluray CD's/.
Small improvement my ass. Blurays can hold up to 500gb.
Cost vs. effect, and I have no idea where you got that 500gb figure, maybe if the disk was crafted by nanomachines but right now blu-ray disks are capped at 50gb at most (dual sided). 500gb ones are not on this planet anyways.
Essentially I'd rather pay a quaint 30-40 dollars for a cheap dvd player then 200+ for a blu-ray player. I'll be watching the same old movies so I won't see much of a difference.
I guess memory storage helps but the cost to switch over to them is a bit too much for my tastes. I'll wait for the 500gb ones.
