I'm a little less grizzled, but I'm so glad I never have to deal with shuffling around broken hardware anymore, much less diagnosing the most inane, obscure bugs due to the hardware slowly crapping out. I've lost so much sleep to shit hardware and unstable, untrustworthy colos. APIs and automation rather than cage monkeys, IPMI, expect and crossed fingers. The Cloud is my church and I've seen the light, hallelujah.
