Not necessarily hardcore pro gear, but gear that pros will definitely use.
Actually, this is pro tool: a 640MB portable raid from the highly respected folks at Sonnet. It's built on 2 2.5 in drives for a crazy small size: 5.9 x 6.2 x 0.72 inches! This is insane, in a good way. Also runs at TWICE the speed of FW arrays.
Iogear makes a number of products that may already be part of your kit, but here's a new one that REALLY caught my eye: a KVM switch with 2 DVI ports! AFAIK, this is the first product like this, allowing two Macs to share a single keyboard, video monitor and mouse (the K, V, and M). I use mine to share a single monitor, kbd and mouse between my desktop and laptop, and absolutely love it.
But this one is ideal for sharing a single Cinema Display or other DVI monitor between your desktop and laptop without resorting to that nasty VGA connector.
This one also has crazy additional features that I've also never seen. Switching a single set of speakers betwen two computers is pretty common, but the one from Iogear allows you to listen to speakers from ONE computer while working on the OTHER. It's called asymmetrical switching, and is one example of KVM switches I've never seen before.
Mine doesn't have anywhere close to all of this. If I'd seen this one first, I'd have bought it in a trice.

Awesome. I had a look see at one of those and the cool part is that it's powered off of the firewire bus so you don't have to plug it in. It does not interfere with the fw bus at all, it just draws power. That means it won't mess up your ioHD connection.
Can't wait to test it out.
