Sharp Japan's Zaurus site
I love my Zaurus 5000, even though I've never really managed to synchronize it with my PC.
I mentioned earlier the new Zaurus SL-B5600. Which is a basically a the same as the existing Zaurus, but with most of its problems fixed.
Really though what I want is the SL-C700 pictured above. Click on the picture to see the Animation of how you close and open the keyboard portion.
It also comes with a full VGA size screen. This coupled with the larger keyboard makes this a really cool pda for doing emergency sysadmin work etc. remotely.
They will not be availabe outside of Japan, which sucks. But I probably will be in Japan early next year in which case I might just have to pick one up. I wonder if I can change the language to English on it? There must be some way.
