those brothers must make a lot of money. Everyone I talk to says the ITSec guys are filthy rich and barely do any work lol.
I personally have a linksys circa 2001. Still tickin. My next upgrade will be after the N standard has been proven and is better supported.
As far as wifi security, here's my take (FWIW): Most wifi security protocols can be hacked in less than 2 minutes by someone "in the know". (exceptions: the chinese government's proprietary WAPI, closed circuit RF connections, cisco PEAP, and WPA with a 26 alphanumeric password - this last exception is still crackable, but will take more time). All of the others, WEP, WPA, WPA2+TKIP, AES, LEAP, etc are very easy to get through and don't require L33T H4X0r skillz. just someone who's bored and can figure out command lines.
I agree with BrianG's previous comments but with only one addition: If you create an OS yourself, it's much harder to be hacked ;)
For those who are truly paranoid, you can always use a LiveCD specifically to surf the net. It's annoying to boot everytime, but considering the entire OS is loaded and operated from within RAM, there's a very small chance of anything getting to your hard drive (including viruses/spyware/etc).
As for people stealing information, well that's pretty much always going to happen. Either through social avenues, or electrical; there's actually a team that has developed a way to sniff your wired keyboard strokes! (http://www.darknet.org.uk/2008/10/sw...ired-keyboard/)
