Hello to all! I've used to using very good pocket computers like Psion Series 3a (1993-1999) and Psion Series 5mx (1999 - till now). I've tried Nokia 9210, was using Sony Ericsson P900 (2004-2007) and then P990 (2007), and Nokia E90 (2008 - till now). Now I use N900, which is closest to 5mx, however its UI is definitely not so mature (yet). Let's improve it!
