I switched my primary PC over in 1999, my secondary over in 2001, and haven't looked back since.
You're in a better place today than back then as finding software solutions to common problems is much easier now.
For other OS needs, just virtualize. I started off using VMware Workstation, after a decade (or so) transitioned to Virtualbox, and now today, virt-manager (qemu, kvm through libvirt).
