Dual-booting needs to become easier and less bug-prone. People need to be able to try Linux before committing their main system. One year ago I tried setting up dual-booting on my system with Ubuntu and it irreparably trashed the Windows boot process; and I needed to do a full nuke & pave. At this time I don't perceive installing Linux to be a good idea unless you're buying a dedicated Linux workstation from System76 or similar.
