Why not replace Windows with GNU/Linux by installing Familiar onto your iPAQ?

I'm running Familiar with GPE on a iPAQ HP3900. GnuPG is available as a 
package - pre-compiled and configured for Familiar.

GnuPG doesn't do the mail component, plus you have the usual problems with 
keeping a secret key protected whilst on a small, portable, device.

At least with a genuine GNU system on the device you can use sensible security 
mechanisms and have a truly security-aware kernel.

Don't confuse "for free" with "free software". The benefits of gnupg do NOT 
arise from the lack of a price tag but from the freedom to modify, copy and 
distribute the source code and compiled binaries.

Don't forget the role of the OS. It's hard enough protecting the device, let 
alone the holes in windows mobile security.

I couldn't even logout on my iPAQ using WinCE and anyone with SynCE installed 
on their GNU/Linux box could read and write all my Windows data without ANY 
security intervention whatsoever. That would INCLUDE a gnupg secret key. I 
could copy / move it off the device or replace it with a different one - you 
wouldn't know. I'd only need 2 minutes alone with your Windows iPAQ.

At least with Familiar, you have an ordinary user with a login password, a 
root user with a root password and a login manager. SSH connectivity is 
supported (and can be secured further) and it has a genuine 2.6 Linux kernel 
with iptables support for a genuine firewall too. It's up to you how secure 
you make your Bluetooth support but it's only enabled after you login.
