they already complain with my setup; I use 2 LT1423 screens and a ThinkPad laptop, two external batteries for work in a unplugged situation and a tablet. All weighs about 6kg.

Each airport I arrive at I have to open this up. My setup does surely not look so 'open' and 'exposed' as his does, but always have to explain this is for work. the US is the worst, Asian countries usually care less... but each and every one.
