Most federal tech execs say wireless Internet is secure - Washington Business Journal:

“The majority of federal employees find wireless Internet boosts their productivity"

You can have a kagillion(?) experts say that wireless is safe for all I care. I do agree that going wireless makes you more productive. I just worry about these "experts"...Really I switched to Linux just to be "safer". I watch my router software to see any "new" connections. Two firewalls? Ha! That's not enough. Studying Network security make you more paraniod, not safer. I cut all of my bluetooth options off after seeing the bluetooth penetration software, forget Paris Hilton! If they really want you they will get you. Just back up your personal files to flash drives...Scratch that, AVOID having any personal files on your pc. If anything, saving things on the internet instead of your hard drive is safer. Buy a shredder and watch anyone outside your house with a laptop, even if they are just watching DVDs...Wait, who's that...*peeking thru blinds*
