Ah the mightly psion
Started with 3s - which taught me what a spread sheet was - and loved tinkering in OLP. Then finished with a 5MX and the IR modem the size of a mouse. How cool was I on a flight back from the US tapping away for the whole flight while the windows machines died and had to be closed down to replace the battery? Palmtop Mag was a delight. I was a fan-girl. Two AA batteries and you were off.
BUT it all fell apart IMHO when they refused to go into colour (impossible to power with AAs I assume). They knew best, not the customer. And they just assumed we'd agree with them. And that was the end of Psion as a handheld.
Palm of course was the competitor but having to learn gestures when Psion asked you to just type on a fabulous keyboard was a no brainer.
What it taught me is that companies who tell you what you do or do not want and are overly controlling (yes, I'm looking at you, Apple) will never have hold of my heart again. I use what I like and want but won't step into the fan-girl world again.
But that keyboard was amazing - if they made one that felt as good for my Nexus 7 I'd be a very happy bunny. The ones I've tried just are not as good. Or is it my memory is lying to me again.
