alert signal

an important TED talk on wireless technologies

i've been *not* worrying about this stuff for a long time, but he makes a few excellent points: not least of which being the accumulation of signals we're being exposed to over time.
i'm now convinced that we won't be going wireless in our next apartment. and that i need a tool like http://www.redmondpie.com/how-to-schedule-airplane-mode-on-iphone-to-toggle-on-and-off-automatically/ so that our phones will simply check for messages at intervals instead of searching constantly. that's certainly not a perfect solution, hopefully one will present itself...
