Great, this is good to know, thank you!

Yeah the VGA thing is optional, but our laptops do need some output, that is compatible to our beamers... :/ Buying an adapter is not the problem :D!

Wow a big thanks to everyone commenting here!! Great recommendations so far (apart from the mac :P </troll> just joking, but for our special case is apple no option, thanks anyway!), I'll check them all! :D

PS: the link to the ubuntu page with certified hardware is great!

I don't want to write a full featured operating system emulator, I just want a VM, that executes bytecode.. <_<

Write a service for people who got the same issue like you: A web(app|page), where people can submit their computer problems like "I need an application, that scans my calendar from <insert calendar provider here> and alerts me in my browser ten minutes before the event comes up". Programmers than could just pick a task from it and post the solution. The whole thing can be expanded to the maximum like payed work, featured idea's, collaboration / team finding based on activity stats .. you name it :) I hope this helps you a bit.. ./sz0ka

I wanted to do this, the most similar thing I've found so far is Assembly Made (https://assemblymade.com/). It's like Quirky but for software.
