I don't have one, but I nearly every day wish I had. I work on database, currently a lot of performance stuff. It's really annoying to do performance work on consumer HW - not enough memory (32GB is the biggest I have seen in portable laptops, and that's what I have) for interesting loads, regular thermal throttling screwing up benchmarks, single socket systems having drastically different performance characteristics than bigger NUMA ones...

Having access to machines remotely can replace some of that, but it definitely costs time.
