one time I was in Kyrgyzstan staring down a band of armed marauders with AKs, me holding nothing but my pre-Lenovo Thinkpad. The battery had long since died (it only lasts about 38 minutes) and of course the WiFi doesn't work due to proprietary drivers but I was able to plug in the six-pound AC adapter to the back of a Unimog and after waiting for the 10 minute boot process to complete I quickly typed "C-c b" which is my personal keybind for blimpy. The marauders were so impressed that they gave me a camel and sent me on my way.
So I guess you could say that blimpy saves lives.
