Who remembers the classic Psion PDA range from the mid to late 90's?

I was always obsessed with these as a kid, before phones and internet they just seemed to be the greatest gadget known to man. Able to carry around contacts, calendars AND tell the world time! The 3 series onwards came with an EPOC OS style system which actually seems to be host to several hundred games (SIM City being the most well known), you can pick them up for around £40 these days running for up to £15 on a set of AA batteries even back then and I'm giving serious thought to picking one up. Any gone down this route? Much experience with the games library?

I'm giving serious thought to picking up a Psion 5MX with it's mind blowing 16MB.
