They're as thick as a Tolkien book and weigh several pounds. They don't have 4K screens. If those tradeoffs are acceptable to you, they excel on pretty much every other metric. They use high-quality standard parts; Linux drivers available for all devices. The design has a high degree of modularity/repairabiity; they're even more field-repairable than Thinkpads. And of course they really are fairly rugged; I can vouch for their being toddler-proof.
It's easy to get these configured for craft personnel; the one I'm using now has RS-232 and MM fiber interfaces... not to mention VGA and SmartCard. No dongles here!
Not to mention all kinds of standard security features... hardware kill switch for the radio; Fn hotkey to immediately blank the screen; quick-release HD cage so you can take your disk with you when you go to the restroom.
They're great machines.
