> Oddly enough nobody ever managed to make PDAs sell as they only appealed to seriously anal business types (i.e. the ones who think having an MBA is actually cool) and geeks with absolutely no life whatsoever.
Actually Psion and Palm did a half decent stab at them. But you missed out a third category - those who need something to help with their crap memory (one of the common features that go with my condition). I had a Palm 3 which worked very well, lasted aaaaaaaaages on a charge (or was it set of batteries), was small and light, and was really easy to use. It took a lot of abuse before I broke it's digitiser ! Then I had a Treo650 (about the time they were being discounted to shift the stock to make room for a newer model) which had the advantage of not having to carry around two devices (phone and organiser). I used that for (I think) over a decade before I finally switched to a basic Android device.
OK - a phone will store phone numbers, but prior to the "smartphone" the functions were fiddly to use. A paper diary will keep track of what I;ve got on, but it's something else to carry - and big deal this, what's in there stays there unless I copy it by hand.
What's great about my current (Android) phone and the Treo and III is that I can keep my address book and diary synced between my phone, laptop, and tablet. It's one of those "so what" things that until you realise how useful it is, you don't realise how useful it is (I hope that comes across as it's meant).
There's also the issue that this allows me to backup the information - so I have no worries like those for whom losing the phone means "losing their life". I struggle to comprehend the mentality of those who keep their contacts, diary, photos, pretty well all their "life" on this small device - with no thought as to what happens when it gets lost or stolen, or simply breaks. I was at the photo counter in Asda a while back, and there was someone in there asking about bluetoothing their photos (hundreds of them) off the phone because the USB port was faulty and it was going back for "repair" (which usually means replacement with a blank device).
