Hey, don't know if this is the right forum for this.....
Just aquestion to GOG; any chance we'll see game demo's posted next to the purchase links?

There's a game demo forum thread on here somewhere. Just search for it.

Here.

To answer your question, I don't think that we will ever see demos next to the purchase links because GOG often does work on the games to increase compatibility with current hardware, but they don't do the same with the demos, so a demo that didn't work due to compatibility issues would give people a false impression of the game.

You can always jusy search for demos on the net. Most work fine on new hardware. Take Giants: Citizen kabuto for example. The game was very buggy at lauch in 2000 but the the same demos from 2000 worked perfectly on my Win 7 x64 machine in 1080p resolution and no compatibility modes checked off.
