I've been asked to consolidate when I've had computer bag, purse & carry-on. Some gate agents will over look it, some not. Now I just put my laptop in the front pouch of my carry on, and take it out before stowing the carry on up top.
It's a pain, and think in the long run, holds up the boarding, since you have to stop and take the laptop out before stowing bag.
Don't flame me! But I do agree there is way too much carry on in some instances. But....It is the airlines making with ever increasing luggage fees, and lost luggage. #1 reason I take a carry on is because the airlines have lost my luggage several times, so I carry-on a change of clothes, shoes, bathing suit, pr of jammies, and toothbrush, etc. No fun arriving on vacay with nothing
The last time did it for me, luggage didn't make my 2nd flight due to delays, flight was arriving at midnight and my luggage was on the next flight. Airline quit 24 hr delivery and told me I had to wait till the next day for luggage, but promised me I would be the first delivery in the morning, after I explained we were only staying overnight at a hotel not far from the airport. We were leaving the next day. Well, there we were with nothing, at a beach front hotel and in clothing we left Canada in

Luggage didn't arrive till 5pm, a far cry from first thing in the AM, and I had to pay for late check out waiting for my luggage. So yes, now I bring carry on with enough to last me at least a day.
