Very smart. I used to run a dedicated offline laptop too, just don't have the need for it as much anymore. Getting used business computers for dirt cheap is wonderful. I'm actually planning on putting up a network of old laptops plugged into 1080p usb cameras and old cell phones for surveillance. There are so many ways to reuse that stuff...
I've had a preference to not use Apple's products for a while. I'm a tinkerer, I like to build, maintain, and upgrade my own machines (and, like, everything else) when possible. Apple has had a tendency to make that difficult. Same reason I'd never buy a John Deere tractor given the need.
