Query: Avoid the demo at least

I tried the demo v.6.005 on my Treo 600. Very impressive for the most part, but unlike the free bundled viewer it crashed very badly on an e-mailed native Word doc attachment. I actually had to do a hard reset and reinstall all my apps and data from scratch. This is a very impressive piece of software, but hard crashes like these (which I subsequently re-tested and found repeatable) aren't really acceptable. Verdict: don't use this if you plan to travel away from your hotsync PC for any length of time!
