OK, define skill for me.
Explain why do you think lag plays any role here. Response of what to what? Packets come and go every 250ms
The guy with the 5 years will destroy the two weeker. Because of experience and skill. What does the lap top have to do with anything?
Look, if you suck in this game, try harder. Dont look for excuses 
Well, considering skill has a different meaning than experience I'll give it to you right from the dictionary:
Skill:
the ability, coming from one's knowledge, practice, aptitude, etc., to do something well
Experience:
knowledge or practical wisdom gained from what one has observed, encountered, or undergone
A skill is gained through experience...not the other way around. And I wouldn't have said anything if you weren't trying to show how uber your cyber nutz are.
I'll dummy this down a bit...a person with a 15 inch screen using a twisty stick has 2 disadvantages, one being lower visibility, it's more difficult to see detail on a 15 inch than a 22 inch, should be pretty self explanatory...the other is a twisty stick does not allow the level of control over a toonplane that a programmable stick and throttle quadrant with rudder pedals gives a person. Anyone who has made the investment and upgraded from a twisty stick to a full CH flight system will tell you, they have much better control.
And lag does play a role in this environment...though I have grossly oversimplified it...response to input, meaning push a button and the time it takes for the system to register that input...a person with 5ms connection is registering data packets to the server much faster than a person with a 100ms connection...in some ways the person with the faster connection could be said to have a slight disadvantage but that is a different discussion.
Just for FYI, I don't make excuses for anything...anyone who has been on the servers while I'm on will tell you that when it comes to flying in toonville, I'm the first to admit I suck and I don't have a problem with it.
