Yep, shiny and pretty, but what is it

and what does it do? I guess you figured I'm not an Apple guy
It's the new Apple Mac Pro, the Macintosh workstation aimed at video professionals, pro photographers, and people with disposable income who want a Mac. MSRP starts at $2,999 for the 4-core processor with 12 GB RAM & 256 GB SSD, and works its way up to $9,599 for the 12-core, 64 GB, 1,024 GB SSD, and dual AMD D700 graphics.
It's about 12" high and 6-1/2" in diameter. All of the expansion is external so you're either happy with what it comes with, or you're turning your desktop into a collection of expansion bricks and cables. Pros don't care. Biggest surprise is Apple doesn't include the keyboard or a pointing device with this Mac Pro. I guess they wanted the smallest box possible.
