I had one. It was very nice, but too specialized to be an EDC for me (I carry only one multi-tool at a time, plus a folder). The wire strippers were definitely appreciated. I can get acceptable wire strips using the hard wire cutters in my Charge or Juice, or the stripping notch in the Charge, though.
As for getting multi-tools through airport security, it seems that any with pointed scissor blades would be prohibited, according to the TSA list. I would imagine, though, that any multi-tool at all, scissors / blades or not, would definitely at least raise an eyebrow.
