I guess it depends on what counts as a PDA. Would you count a Blackberry? They sold them as PDAs when I got my first BB. But it wasn't really at all like a PalmPilot or one of those Motorola dudes.
DVD-R big time. I specifically got a recorder as my first player since I knew I would be ripping discs a lot.
WebTV came out when I was too young to afford a TV, and my parents wouldn't have gone for anything like that even if I begged.
Never had or wanted a 3D TV, as my first time hearing about them was literally seeing them in action and the effect was headache inducing. The Nintendo 3DS used the same tech, and I always kept the 3D slider at the minimum.
I do want a Raspberry Pi or some other micro computer; I just need a project and reason to get one. I have a 3D printer so I have too many awesome choices I could try.
I might have gotten an internet radio player... If I knew of their existence back when they would have been relevant. I was big time into Winamp's net radio scene in high school. Even ran my own. Reading your list was the first time I was made aware of them, though.
I am 38. I've never been on the bleeding edge, but I have tended to be an early adopter. If enough people try a thing and say it's cool, I come check it out. lol
