Until now, that is. It's no fault of the case itself - I think it'd probably last another 20 years or so - but rather the ever-changing TSA that leads me to switch. When I got home late last night, there was a new checkpoint-friendly soft-sided briefcase waiting for me. I just moved everything out of the Halliburton into it.
It'll definitely make dealing with the ^&^&$#$%^#^*&(* TSA easier...but I'll miss the old one. Strangely enough, my next trip is one where it probably won't make much difference, at least on the return...but that's a subject for another post.
