Since my damn T-Mobile service doesn't work at all in the cave of an apartment I call home, I'd be interested to check out the Zen by Spotwave Wireless. Using patented technology to prevent radio network feedback and interference, this wireless product promises to "dramatically" improve indoor wireless reception for spaces up to 2500 square feet. It also emits low power to cell phones and other devices to extend your battery life—Wha? Not a bad extra feature. Look for the Zen second quarter of next year for about $400.
