Portability on MBP's

I created this thread under the Video heading because I needed an opinion.

I don't own a Mac yet but I am saving for one.
If anyone does any video editing, do they use the 15 or 17" MBP? How much easier is the 17" to haul around?
I've seen seminars with people who drag their macs with them and make presentations with them, but I can't determine which one they are using.

The 17" is not to bad to move around but it is heavy and big. I have a 15" now but I used to have a 17" and I got smaller one as it is much easier to haul around.

I'm just going to have to take a trip to the Apple store and play around with theirs.

Thanks B&O for the reply!

always a good idea to get your hands on the machine before you buy

as for the portability, I have a 15" and I cary it around all day and it's pretty good ... I mean I had a 14" laptop before, so for me it was a bit large at first, but as I said, I cary it from room to room all day long, either in a backpack or just in my hands - doesn't get in the way, doesn't feel heavy, it's very thin - ideal

don't know about the 17" since I have only seen the previos generation

but from time to time I do see people with the new 13" and I just can't help to think that it's just more sexy than the 15"
