Actually, it doesn't really matter how fast a writer can write 'theoretically'. The writing speed increases from 0x to whatever x at the edge of the disc. The difference between 16X and 24X is only 40 seconds or so. You'd think it would go faster, but the differential change in time per unit speed is exponential, not linear. So if they came out with 48X writers, you probably couldn't tell the difference between it, and a 24X or 32X besides the logo on the front
. Unless they increased the density of CDs to over a 1 GB, then yeah - it would make much of a difference. Otherwise, on a normal 650-800MB CD, the increase in speed will be a waste.
