I'm at the same point as you, after 30 years of sticking with MS, must be the Stockholm Syndrome affecting me, but now waking up and realising that I should escape from being locked up in the MS basement being abused there for way too long.
Already have an iPhone after MS royally fecked up us Windows Mobile user, and an iPad after they withdrew their tablets. Now they are fecking me around with Windows 10, I should have stayed on 7. Three times fecked, goodbye MS, you had more chances than any sane person would allow you. I think I'll "Just Do IT"
