I use it to tether my Thinkpad via a variety of Android devices. It
had a tendency to panic the system for a while in netbsd-7, but
netbsd-8 has been very stable for me.
I even use it when my iwn occasionally has issues connecting to some
wifi APs - USB tether to android phone, then just connect to the wifi
on the phone.

In short - I don't leave home without it :-p
