I was a great fan of Psion devices and I have a small collection of their products .
However I now use a Blackberry for keeping in touch , checking mail , looking at my diary SMS even phone calls etc . But it is too small to handle long emails or read attachements . and too slow (and small) for useful web access .
Just got an Acer Aspire One this is a Netbook running Linux brilliant but it wont fit in your pocket .
