Hello everybody and many thanks for your replies and suggestions
We already thinked about all those issues and we would like to try it anyway but with a good product and as a test for the moment. Actually, we use it as paper and it's updated daily and takes a lot of work to print it on the special paper sheet that we have in A5 format. The paper is very special and cost a lot by the way and it isn't very easy to do all the printing stuff for the people concerned. That why the fact of having a template in Word or Adobe Acrobat and just save it and put it in a SD card sound just perfect.
I know that we may have some device disappearing but that's ok. Btw they might be used only as menus, so they shoulnt go so far away. And finally, this is for a very selective kind of customers... in a very specific place (can't say more of it xD)
I saw that the Kindler DX seems to be good, nice and 9 inches. What do you think about it guys?
Thx again for your replies
