I don't think any current laptop displays pass muster for editing in the studio.
Laptop displays are too bright, too contrasty and offer not nearly enough manual adjustments to do a precise calibration.
I'm hoping that in the not-too-distant future that someone (Apple?) will come out with a laptop with pro-level color controls.
Until then, any editing done on a laptop should be reviewed/adjusted later on a better (desktop) display.
For this I'll cast my vote for LaCie. I think they offer the best price-to-performance and have for many years. If money is no object, the Eizo displays are currently the best available. Samsungs are great, too, somewhere in between the others in price with excellent quality.
Whatever display you use for any photo editing, training your eyes is always necessary to understand how the colors in your photo will reproduce on different devices.
After all, if you're having prints made or sharing your work online, it's more important that it looks good in other conditions besides just your own screen.
What's your take on the Apple cinema displays?
(And there should be a new line coming out rather soon with LED backlighting)
