Actually - I followed the advice from TSA screeners a total of 8 times on my 4-flight trip. (Cigarette breaks - doh!)

Every time I removed my PC from my backpack...and every time it went through without a hitch. It was never selected for secondary - nor were any of the bags I brought with me.

I told the screeners about the PC every time I went through security - and it seemed to work. As far as why I asked the TSA agents on the board...well - they certainly know best.

So thanks for the advice - it payed off...and I had absolutely no problems.

Thanks!
