I got my 860 about a week ago from the guy in this thread:

Mine arrived before I expected but some people ordering after me seemed to have experienced some delays.
To answer your other question, the Sharp ROM isn't bad. I didn't see any Japanese dialog boxes while I used it. After I had the Z for a couple of days I switched to the Cacko Qt ROM. This is working out just great and I would suggest you make the change as well. I have zero experience with Linux, but if you follow the instructions in the Cacko thread,
http://www.zaurususergroup.com/index.php?n...iewtopic&t=3159 it's simple to install. Make sure you install the Hotfix as well. The 860 just feels better with this ROM.
The keyboard is pretty much an English keyboard. There are just a couple of keys that just have Japanese labels. I have no idea what they do, but I've seen a post somewhere explaining.
I'm really enjoying my 860, I'm sure you will when you get yours as well.
