Does any Developer has already experience with the Apple M1?

Don't have access to one, but I've seen people using XCode and VSCode in videos/posts (VSCode via Rossetta iirc). XCode was reported to be much faster in compiling (also someone compiled Rust and reported it as 2x as fast as in their Intel Mac).

> Also very important, Virtualization. - What did you tried? - Which road blocks occur? - Is a form of Bootcamp available?

Parallels and VMWare was announced support. Not sure if they already have it out, but Parallels was demoed during WWDC running Linux-on-ARM. Docker also made an announcement that it's coming soon.
