A new review has been posted for the Zaurus SL-C750. This PDA (as are all C-7xx PDAs) is only available in Japan through Sharp, but the folks at Dynamism.com have translated the OS and applications into English, provide lifetime warranty, etc.
This is a detailed and very favorable review of the device (actually, all reviews I've read have been quite favorable, but some others tended to be a bit more reserved), and is well well worth the read if you're currently considering a new PDA.
Here's the full review.
