I have had the new Zaurus SL-6000L for a few weeks now, and all I can say it is still an amazing chuck of hardware with a killer OS (Linux).  I installed all the applications I had on my old Zaurus in about a day.  It is very snappy and runs well.  I was fiddling with playing movies on there, I will post the command I use in mencoder when I get home.  It plays movies pretty decently.
