This was a proper PDA rather than a smart phone (I refuse to accept what Apple "invented" smart phones). So a large screened Windows CE device with a stylus.
Maybe I was looking in the wrong places but there didn't seem to be much free stuff for Win CE back in 2002.
WinCE devices were much more business oriented than Palm, probably because they had in the beginning a much smaller market share. So your experience was likely representative for this platform.
I completely forgot that they were around at that time.
I didn't get the impression it was more business oriented than Palm. I mean CE certainly had productivity tools like a cut down version of Office and support for Active sync (which I hated). I think the real problem was Windows PDAs of that era didn't even share a common CPU so you'd have multiple versions of software targeting different chipsets. I'm pretty sure that would have put a lot of developers off. But there were a few gems on the platform, like Tomb Raider (which actually played really well).
I might had a dig around and see if I've still got it. Might be a fun device to repurpose.
