Simply awesome on my Ti Book. Finds 802.11b networks with aplomb, and tells you important things like signal strength and whether or not the network is WEP-encrypted. Through the app's audible cues (mine's a female voice), any wireless net that's found is read aloud when it's encountered. Perfect for (white hat) wardriving. No more endangering other drivers or pedestrians while looking down at your laptop screen! Plus, I selected MacStumbler's audible "ding" to tell me when a non-WEP wireless network is encountered and the "bonk" sound to tell me when a WEP-encrypted network is nearby. So, when you hear a "ding" from MacStumbler, you pull over and hop online! If this had support for Wirelessdriver and external PCMCIA wireless cards (to help Ti Books get better wireless range), it would be indispensible for wardriving. I...LOVE...THIS...COMPANY.
