Thanks Joerg for pointing me to the Neo900 project. I forgot to say that my N900 is much better for drawing or for taking handwritten notes than my Android tablet or other devices I have seen (not tried the Samsung Galaxy Notes but seems too much work around). Thanks to the 'old-fashioned' resistive screen and the stylus. This is why I also miss a bigger screen. I liked very much the program Xournal as it worked in my Nokia N810. I also prefer to have a physical keyboard in the slider design. You can either work only with the screen with the keyboard hidden or with the keyboard when it is out.
