i would personally go for a toshiba, they are very nice laptops and have tons of options and stuff.
EDIT: i dont know how computer savvy you are, but if ur looking to do video editing and whatnot, you may wanna look into a new intel based mac. mac has the best software for editing pics and video. you can also go ahead and download the boot camp disks and dual boot windows for doing other things that you would need to do. i would do that and of course get a dual core processor
