I have been wainting for your answers and suggestions all these days.
Thank alls for your time and help.
Some thoughts: first of all, an umpc with a very high price isn't acceptable because we should have an irex that makes annotations highlighting.
Secondly, i have seen some devices with windows CE with low price. I am afraid that with these devices will be difficult to find additional programs, like greek language etc as i could do with xp.
Finally, i am not sure if is better to wait for windows 7. I think that as a result of new windows we would have many choices in new umpc. Does any one knows something about this? I am waiting for your opininions suggestions.
