MACBOOK VS windows based laptop

hi ,
i'm going to buy a new laptop .
does new macbook 2.4ghz 3mb cash perform well in windows too ?
in 1500$ range there is another option HP art edition 2.5ghz 6mb cash , 320gb hard , 4 gig ram .
which one do u choose ?

tnx

merC maziar jan ,
i'm mostly using windows , but i like some programs like shake or final cut that only runs on macs .
but anyway , does windows performs as other windows based laptops on macbooks without any unexpected latencies or problems ? and does 2.4ghz 3mb cashe on macs performs that much slower than 2.5ghz 6mb cashe on hp art edition ?
i mostly use video editing programs and 3d programs but i also want something that gives me some battery life , what about their battery ? my old hp under 100 cpu usage gives me 50- 80 minutes , what about macbooks ?

and from all points of views which one ?

Agreed. Macbooks are for average users, and even at that, they're overpriced. You would need a Macbook Pro. You can get much more power from a PC for the prices those go for.

I still maintain there is no reason to get a Mac over a PC. I've never found one, I doubt I ever will.

Unless you need those mac apps, which I highly doubt there aren't better programs out for PC's, I would get a PC.
