I doubt there's a single one. Determine your budget and get the best combination of features that work well for digital photography. Look at things like the processor, amount of memory, storage and video card. Digital photography is not that demanding and the performance difference on a $800 laptop and a $2000 laptop is not going to be that great for simple image editing and retouching.

Digital files are some of the biggest files there are, so handling them and remaining strong performance wise is a real challenge for laptop users ......(drum roll)...until now....late 2008 early 2009 started the new generation of moble processors, with faster front side bussess like those found in desktops, and higher ghz and larger L2 Cacha. which again, were before this time, exclusive to desktops. Be careful of the retailer trying to sell the slightly outdated processors for the exact same price as the newer ones, without letting on what your missing and why you might not want to go with yesterdays laptops...Digital photograpphy was once tackled efficiently only from a desktop, where the formentioned computer attributes are present, and ready to perform as a workhorse (core two duo two processors working side by side)...without heating up a small room or shorting out the fuze box. Todays moble chipsets are smaller, more energy efficiant and pacfked with power only seen previously in desk tops. My advise is, stay within your means, but by no means, settle for anything less than the new moble chipsets that offer 1066 FSB and L2 Cache's up to 12 mg. I have one of the first quad core laptops, and it rocks. Remember, one "horse pullng the cart is nice", "two is nicer" ...."Four" well, you see where i'm going. ..... and never chimp out on the RAM it's expensive but a must in any video processing field edevour. Good luck. Remember to look at the stats. Don't settle for yesterday when it costs the same as today.
