Well I can add Istanbul to the list, although they tried putting the whole bag through first. I guess the scanner couldn't make it clear because of some other things in there. They asked me to turn on the lap-tap, which I couldn't do because the battery had died. They then put the lap-top in the scanner (carefully and by hand!), agreed it was OK, and handed it back to me with a 'thank-you'. I'd put up with that anyday.
Incidentally, what is it about lap-tops and cam-corders? My carry-on bag contains everything that might have an electrical connotation - shaver, camera, mobile 'phone etc. No-one asks for them to be individually scanned, my only recent experience of having the bag searched was at a UK airport (LHR, flying Virgin to SFO, selected for random search).
