This was your LIE: and there is a WORLD of differences between the designs and if you can’t see the differences you are being deliberately obtuse!
I never said ANYTHING about there not being differences, you saying that I did is you LYING, which is what you always do.
The Psion was the first PDA. Those are the facts, Newton was NOT first. Yes Newtons had more features, but that just makes it another example of exactly what I said, Apple taking an existing gadget (the PDA) and adding widgets (like a calendar) and then the lying fanboys insist Apple was first. They weren’t, Psion was first, by 8 years.
The psion was NOT a Personal Digital Assistant. It was a limited purpose hand held computer with a single line passive screen and an awkward user interface. Just because YOU and other Apple trolls want to call it such when it lacked basic organizer applications like a clock, calendar, reminders, and basically had just a limited address and phone number list with a small note pad capability with a 4K memory limit and was called a "pocket organizer" it was by NO MEANS anything like a fully capable computer! It was more a glorified calculator. I had a digital watch that had many of those capabilities by the end of the 80s but IT wasn't a PDA either. . . And it DID have a clock and calendar!
If you want to stretch fact like that to include the Psion, then the TRUE first PDA was a spiral bound 2" x 4" note book and a pencil my father carried in his shirt pocket for fourty years. He kept his appointments, his addresses and phone numbers, a collection of poems, some drawings and plans for inventions ( a couple he patented!), important dates, thoughts(!), notes, reminders, and a host of other things in that notebook/PDA. He's been dead since 1995 but I still have that PDA and there are no batteries to run down and the pencil doesn't even need sharpening; he upgraded to a mechanical one sometime in 1991! But the erasure mechanism leaves a lot to be desired. . . it leaves smudge ghosts now. . . easily read remnants of what was erased. Best of all, it has far more than 4K of capacity! My dad, though, before he died, was getting close to using what capacity it had...
I had a Casio data watch that had more functions than your Psion and it included a phone dialer, long before your Psion.
