...quality of the technology. Betamax was better than VHS; the Mac operating system is superior to Windows. Even in the transportation business, there is the cautionary tale of Preston Tucker, who in the 1940s designed a "car of the future" packed with such safety innovations as a padded dashboard, disk brakes and safety glass--a car so far ahead of its time that only 51 were ever produced. In fact, the annals of high-tech history contain remarkably few cases in which the most innovative technology has emerged triumphant in the marketplace...

...recall with nostalgia your computer’s first days out of the box: a simpler time, when she hurtled through her self-test; when the nifty “Available Disk Space” piechart showed seven gigabytes of untrammeled roominess; when windows and menus sprang from her toolbars like a great splash in a clear lake; when your desktop sat empty and content, like a mid-day showing of Serendipity. What is it, then, that drives us to engage in unprotected interface with these ill-intentioned download sites? Certainly this irresponsible behavior is not a means to some...
...Healthy disks are like a car's shock absorbers. A soft, gel-like substance in their center, or nucleus, helps cushion the jolts caused by simple movements like running and jumping. But for various reasons, a disk's hard, protective shell can degenerate, allowing the spongy interior to bulge out and press on spinal nerves. This can cause excruciating pain that radiates down the leg in a condition commonly called sciatica...
Nucleoplasty (literally, removing the nucleus) is aimed at relieving that pressure. Using only local anesthesia and light sedation, which allows the patient to remain awake, the doctor inserts a needle into the distended disk and is guided by an X-ray imaging system that reveals the needle's position at all times. A wandlike device is then threaded through the needle and into the disk. There it emits a burst of radio-frequency energy that heats and almost instantly vaporizes the excess tissue, providing in turn almost instant pain relief...
