If you have $2000 to spend, it will be hard to beat the 19" Pre-dell alienware Aurora mALX

Especially as you are a designer with requirements.
Not everyone has two grand burning a hole in their pocket though. The best part is that now that you are in the market, just about any $1000 laptop will handle what you want to do, and comfortably.
I would suggest spending some time looking at what Toshiba has to offer in the Satellite line and the Qosmio line. I find personally that Toshiba is a very dependable brand, especially considering how long they have been making laptops (First to make a PC laptop, IBM based system in 1985, first to add an optical drive to a laptop, first to add a DVD drive to a laptop, etc.). Really you should be happy with the performance, durability and security of any Toshiba you purchase.
Avoid anything HP. Out of the factory, the DV9000 series are showing up left and right with left hinge problems. They are flimsy. I've seen way too many with motherboard problems, especially right after the default 1 year warranty ends.
Sonys are just too overpriced for what you get.
And of course, you can't really go wrong with a Mac. Any... Mac.
