It's a smart little thing but does make me wonder if it's really worth £220 when you can buy a used Toughbook with a bigger screen for less, or a brand new full size laptop for £330.
Incidentally, all this talk of solid-state HDD's being more robust is fine but has anyone ever read the impact specs for a 2.5" hard drive? The manufacturers rate them for 250G shocks during operation, it would take a case-crushing impact to upset a HDD, let alone cause serious damage, at which point you've got bigger problems anyway.
