Like:
- Atari 2600: The mother of all consoles. I only need the H.E.R.O. cartridge

- Atari Lynx: Quite ahead of it's time, quite some Amiga spirit in there, and the devkit was based on Amiga
- NES: Despite other opinions, I really like the controllers. Form follows function at it's best. Some really great games. Have a look at e.g. the NES version of Gyruss.
- Playstation 1: The perfect console in the emerging 3d age
- PSP: awesome device, but what I don't like about it is how Sony locked it against homebrew stuff. Hopefully there will be an Eloader for 6.20 soon.
- CD32 (I guess, unfortunately I never had one, but it is an Amiga)
Dislike:
- everything else from Nintendo (maybe I am just too old for that stuff)
- All the Xbox stuff: Yeah, I admit it: because it's from Microsoft.
Never really had the chance to try the Sega stuff, so I can't say anything about it.
