Heya, I recently had the pleasure of demonstrating BeOS to the 3ivx development team. I thought I would write down my thoughts from that demonstration. The audience was composed of pretty much Windows developers with 1 or 2 Mac OS developers. OS Features that impressed them: Copying and Moving files with a right click. Indeed I think they rather liked the way the right click worked for most things. Replicants made them sit up and take notice. The idea of being able to extract pieces of an application and embed them into the desktop was something that they really liked. Multiple Desktops. Just like having 32 monitors only virtual :-) Super Fast find, nothing like an indexed query. :-) Live Queries, setting up queries and watching them autoupdate as you copied files around or created new ones provoked a lot of discussion about how it was done. Changing Windows to display attributes so you could render a list of files with the additional details Apps that impressed them ProcessController, they liked the way you could see everything working while you examined the processes. Problems The version of BeOS I was given to demo on had BONE installed, I was not very familiar with it and it crashed a few times. The developers used scp and ssh a lot to move files about so a good network stack is a requirement. Summary Obviously BeOS is not Haiku (So why am I posting this here). However, BeOS is our inspiration and I thought you might be interested in the areas that a 10 year old OS still manages to impress with. -- Cheers David
