It's good to revisit it fairly often, but at this point, there's just not
heaps of exploit code out for them. By the time that there's a real
threat, we'll likely have more options for protection. At this point, I'd
seriously look more at strategies for keeping them up to date- since we're
likely to have more of the same client-side "it has to go through the
firewall" problems anyway. I doubt that PocketPC has (but I haven't
looked) all that many dangling services, but I'd bet the Web and mail
clients are about par for the course.

Yeah, I just think that at this juncture, a firewall is more of a placebo
than a valuable control. Now, that could change, and if it does, then
ability to have on in place becomes important, but I really don't see it
as a major threat vector for a while (I bet the loss stats for PDAs well
outweigh the attack stats, which well outweigh the successful attack
In fact, I'll go out on a limb and say that I doubt there's been a real
PDA attack in the wild, even with 802.11 (and I'd concentrate more on WPA
for folks who use them at home than I would a firewall...)
I'd also hate to take support calls for things that "don't work" on a PDA,
since lots of salespeople *need* them to work *now*. If there's an
alternative browser like Opera available, I'd be looking at rolling that
out well before a firewall.
Just my .02.
