These look really cool, but what is the target market for $3000+ desktop machines? I don't doubt that there are some people who could take advantage of that much power on a desktop, but it seems like kind of a niche product. I work with machines that do use their 256GB of RAM, but they're all servers. I'm a Linux user, so maybe the thin workstation model feels more natural to me. My MBP has 8GB of RAM and I rarely even come close to using that much, even running two or three VMs at a time.
