Well this hasn't been too conclusive, but since I've now got the mini I can afford to experiment more. I'll wait for 3.5.4.1 to come out and try it. If I don't like it, I can always upgrade from my current rc12 to the latest pdaxrom. Thanks for all the input.
On a side note. The mac mini is so far turning out to be a real wiz kid. It has fetchmail, procmail, postfix and even sendmail installed by default. In this little package I have bluetooth, wifi and ethernet and they were all extremely simple to configure. I'm suspicous of the default firewall. There's plenty of the underlying OS to checkout, but I'm happy with it's quietness, small size and little heat dissipation at idle. OSX is pretty good with the "it just works". You sacrifice flexibility, but you lots of flexibilitywith the unix part of it.
