The 5mx would have won "best ever", except that it has an awful screen, especially compared to the magical screen of the Series 3a (it actually got worse shen Psion added backlighting to the Series 3mx).

I really don't understand how Psion let that screen pass, given their track record on product quality design. It's not as if there wasn't any better technology available at the time. OK, granted: not much better, but still...
