For all those espousing the benefits/rights/convenience of taking your possessions with you, might I suggest you do a bit of research about "flashover" fires? Perhaps this might educate you a little on the risks of delaying an evacuation and why some of the Professionals on here are getting so vociferous about it.
The modern travelling public seem to have a "I know best attitude" hence the inattention to the safety demo, mobile phones going on as you rollout on the runway, standing up whilst taxiing in etc etc.
Please, for you own sakes and those around you just be a bit more adult - it might just save your life.
