My "main" machine is a 30 year old Viking 990. I told my DH that if it ever goes out, I'll pick one of our other vintage machines for my main sewer. I looked at new machines, and just can't warm up to all the electronics, and I doubt any of them would last 30 years. The 990 is the first generation electronic Viking and it's got enough non-metal in it that I don't expect it to last to meet my lifelong sewing needs. But I know I've got many more machines that have been around for 100 years, and could be expected to be working as well in another 100 years.
