After years of hemming, hawing and waiting for televisions to make the jump to digital, the very first "Super Wi-Fi" network went live in Wilmington, North Carolina yesterday. Now, Super Wi-Fi is a bit of a misnomer: the technology isn't really Wi-Fi at all -- it utilizes unused "white space" spectrum in the analog T.V. bands, instead -- and it's waaaaay slower than normal Wi-Fi to boot, with speeds up to 22 Mbps. So why is Super Wi-Fi's launch such a big deal?
Every now and then you need to check the performance of your system. Maybe it seems to be running sluggishly. Perhaps you just got a new graphics card, or doubled your installed DRAM.
