apropos nothing, I have to say that my Psion 3a is the most used and useful computing device I've owned (i.e. other than the nice FMS/EFIS/TCAS/GPWS etc which I don't own but stops me killing myself)
It does my diary, replaces my deteriorating memory, does a 747 manual loadsheet (with trim envelope), holds my pilotlog, tells me when it's sunrise/sunset (like are we going to have the big reactor in our face on the approach), wakes me up (but make sure it knows where it is

), confirms that really is Mars looking so bright (thought that would impress the boys but it didn't), does word processing, computes a lot of nerdy stuff etc etc.
What a pity the line is gone
