Liam, quoting me:
   But why
"former Psion 5 owners", on this list of all places?  I have never
 owned a Psion 5 - but I use my Psion 3c daily! 
 Well, true - but there is nothing quite like the Series 3 any more and
 I don't think there ever will be again. Frankly, although there were
 things I really missed about my various S3s, the S5s were better in so
 many important or significant ways that I never considered moving
 back. 
 
Sorry if I sounded as though I was starting a Psion 3 vs 5 war.  That
was far from my intention!
I was merely saying that this is Classiccmp!  You don't look on
Classiccmp for _former_ owners of nice machines, but for people who
still use them!  And not just the Psion 5 - your post is equally
relevant to people like me who use the 3.  Or the HP 95, 100 and 200
palmtops.  Or plenty of other machines.
  I preferred the S3 interface, the keyboard shortcuts,
the file/program
 manager and much more, but the S5 was so much more capable, I never
 regretted moving.
 I'd give a lot for a modern S5 type device, but I would never go back
 to an S3 today, I'm afraid... 
Fair enough.  I'm not criticising you for it.
I got my first two Psion 3 machines when they were withdrawing the Psion
5 at work.  We were asked to find any Psion 5 machines lying around and
send them in for recycling :-(  On a shelf we found a box with two Psion
3c machines in instead.  Since we hadn't been asked to return those, I
kept them.  (With the former user's blessing, I may add)
I never had much exposure to the Psion 5.  I don't much like touch
screens [*] - and the touch screens of that period wore out quickly,
IIRC - and the hinge on the 5 was even more complicated and liable to
fail than that on the 3.
So what was nice about the 5?  I'm not asking you to justify yourself;
I'm genuinely curious!
On the subject of Psions, the two common failure modes on the 3: cracked
hinge, and leaky backup circuit.  By the latter I mean something in the
circuitry that remains active when the main battery fails - clock,
memory, not much else - starts drawing excessive current, and the
machine flattens the backup cell in about a day, whether the main
battery is in or not.  Does anyone know what causes this?  I have two
old main boards with this symptom, which I must reverse-engineer.  One
day...
Philip.
[*] ... but prefer keyboards.  Which is why your original post was so
welcome!
