Sharp has created 2 series of linux based PDAs:

- 5x00 serie (5000d, 5500, 5600 models):

- 7x0 serie (sl-700, sl-750, sl-760 models):
http://www.linuxdevices.com/articles/AT5295837592.html

- Recently sl-860, same hardware as sl-760


I think that 5x00 serie has been sold in Japan, USA, United Kingdom and Germany.
7x0 and 860 serie has been sold in Japan only (as far as I know).

I need to know:
1. In which countries Sharp really sold these models ?

2. How many units of 5x00 and 7x0 Sharp sold in these countries (2002 / 2003) ?
(860 serie is too new so it's not important if you don't find informations on it)

For the question number 2, I wish answer like:
Japan / 5x00: x units sold.
USA / 5x00: x units sold.
Japan / 7x0: x units sold.
...

Thanks for your help.
