The WarpUp stickers should make your Amigas fly :-)
As for p.OS-pre-release: It's a pre-release of p.OS (duh). It was a shot of a German company (ProDad, I believe, too lazy to grab my copy of it from the cupboard to verify) to create a replacement OS for classic Amiga hardware. Until that moment, ProDad was known for some software-titles mainly for adding titles to video and do some rather nice video-swipes. p.OS never realy took off but somehow I did like it (the CD comes with a Chess game that even I could beat ;-)). Have a few hours of fun with it, you won't be too disapointed.
I have some experience in programming C on.... Windows (the boss made me do it!).... and had a go on it with the Amiga but decided to take the easy route again and stick with AmigaBASIC like ACE (for the moment).
If you've got the hang of C you could have a go at porting Firefox on Classic Amiga ;-)
