And this equipment doesn't have any problems with being in space? (ie. radiation, etc)If (or when) they fry, they replace them. Apparently it's cheaper.Yep.These laptops do have modifications from the normal consumer-grade equipment. They have locking power connectors, and coated circuit boards to prevent arcing.The "real" ISS control computers, the MDMs, are rad-hardened.

That offset is interesting. They looked to me to be in trail and that would seem to make sense and be necessary for a docking tomorrow.

They had to be modified afterward?
Why would there be a problem with arcing on the ISS? Are there static-charge-buildup/grounding issues on ISS?
Somebody at SpaceX is munching on potato chips.A lot more getting up and pacing being done by the NASA people.What's the blue ring on one of the monitor windows for the guy sitting at the back? Is that a Quicktime logo, or some kind picture of the Earth?

But if the air in ISS is clean and filtered, I can't imagine that it would pose a foreign object debris problem for electronics.

At least as long as you don't take them to EVAs Additional hardening may only marginally robustify them, but it does make sense considering how much does it cost to lift every kilogram up there.

These days you can buy cases that let you take them underwater.
