My paeans to proper keyboards on PDAs and the Psion!:

My dream gadget would be a slightly smaller 5mx with colour screen and builtin phone etc:

I've not found the Psion too bulky myself (I had the 3a before that, I think), but then I carry a bag or small backpack round with me. It would be much easier to carry it round clipped to your belt if Krusell made a case for it (I love Krusell's system - I've emailed them asking why they won't do a case big enough for a Psion, digression but if other people would like to lobby them too then maybe they will? http://www.krusell.se/contact.php. If I could carry my 5mx around with me constantly that way, I'd be deliriously happy. Errr yes, I love my Psion!)
I agree the screen is worse than on the 3a, but I use the backlight when necessary, and I've got used to it especially with the ability to zoom. One plus about the screen not being that good is that it's harder for others to read it over my shoulder on the Tube! (I have a rigid backpack which turned on its side on my lap does very well as a mini table to rest my 5mx on).
I've never found anything with a keyboard as good as the Psion's which is why I still cart it around with me.
I've tried handwriting recognition on a touchscreen and the Nokia 7710's is very good (see my 7710 review here if you're interested). But still it's not as fast or as accurate as touchtyping with 2 hands.
I've also got a Blackberry through work, but again if you've tried a Psion and you're a touchtypist then the Blackberry just can't compare.
So like you I've been waiting for a mobile which could be a Psion replacement.
I'd looked at the Nokia Communicator series and they were definitely too brick like. So I've been seriously considering the Nokia E61i, which I know is more Blackberry-like than Psion-like.
I notice from Rafe and Steve's review that the E90 keyboard isn't exactly fantastic, though that seems to have been a pre-launch version. More tellingly, I found this review from The Register which said, and I quote:
"Echoing around the web yesterday were many comments proclaiming the phone as the first communicator worthy of the Psion legacy. With the Psion Series 5 and even the Psion Revo, it was possible to touch type two-handed. Alas, unless you have very small fingers indeed, you're going to be disappointed. So you're really obliged to use your thumbs.The reality is even worse, however. I found I made more mistakes typing on the E90 than I do on an E70 or an E61, which really are optimized for minimizing thumb input errors, particularly the E61, with its widely spaced keys. I made even more mistakes on the new communicator than on its true predecessor, the Nokia 9500. And nothing about the experience suggests I'm going to adapt to the device.
Why, I was left wondering, did Nokia go to the trouble of creating such a large device to house a full QWERTY keyboard when the final user experience - and in the end, as Apple knows, this is what really counts - is so poor. Was it simply to demonstrate its technical prowess? To beat the world record for the longest feature list in a smartphone?"
The article then goes on to point out, which I didn't know before but it explains a lot, that:
"Veteran Psion users will recall how the company used clever patented hinge designs to maximize the amount of space available for the keyboard. This trick bought precious square millimetres of space for the keyboard. (Psion's design company also invented a new kind of key design, giving the keys additional 'travel'😉. Even though Psion doesn't use the IP in its products any more, it won't license the patents, we're told, so no company can recreate the Psion experience. If that's really true, then Nokia should buy the rights outright, rather than continue to develop products that can't deliver a user experience it promises."
Does anyone know anything more about that? Why on earth won't Psion license those patents or sell them? They'd make a fortune. There must be armies of people like us gagging for a decent mobile/PDA combo with a proper Psion-like touchtypable keyboard.
Sorry for the long ramblings, I guess personally what I'm going to do is try out an E90 in the shops and see if the keyboard really is that bad, and I'll probably go for that or the E61i depending on which one I find quicker for data entry.
Someone (ideally Nokia, or else Sony Ericsson) please please please go and buy Psion's patents!
Meanwhile, if anyone has had experiences of comparing the E90 and E61i, or just what the E90 is like, I'd also be very grateful to hear them.
Cheers
