Mbp
I have a MBP and I love it, and I'll admit that I'm in Windows every once and a while, but thats for games...
But look at what you need:
Gaming - the MBP can handle that
Travel - Its light and thin
Web - No Viruses!
Video Editing - A free decent editor, and two very good professional options, I <3 editing video on this thing, no rendering because of the decent gpu is epescially useful
Windows - you can also run windows...if you really have to
The Dell:
Not as thin, heavy? (dunno weight but they usually are bigger)
Web - IE yuck, but even using a different browser there are always those damn viruses
Video Editing - As far as I know the free editing is crap on Windows still, and Premier is pretty good but nothing like the tools you get with FCE for example
And don't let posts about broken laptops n such discourage you on these forums, if every person posted when they got a non-defective laptop...well...the forums wouldn't be very interesting would they
As for the shipping, it took like 3 days to get to me from online. If you buy it at a store and want a certain configuration, they may have to order it for you anyway cause I think they only sell the stock 2.2, 2.4, then 17". Prices instore are the same, and I got my free ipod and printer online, so I know you can do that, but I also think you can do that instore. sorry I just know read your other post I some how missed <.<
