Yes, WPA Enterprise among other technologies. ;-)

But seriously, my comment was about implementing 802.11g in general, not
about lack of security on the TX itself. Many 802.11b-only APs don't
support WPA or WPA2 (and cannot be updated to it), so you can argue that
it makes sense to migrate to g for security purposes on the AP-side.
(Yes, not required for hotspots. ;-))

I agree. If I had to contend with 802.11b devices I might just consider
running 802.11a--albeit with more APs--in order to keep my Wi-Fi
separate from my "Low-Fi." ^_^

Indeed I almost considered buying the 802.11b sled for my Treo 650. I
declined due to several reasons--and the fact that it had b-only was one
of them (but probably not the primary reason, believe it or not).
