Read the press release here.

Edit (some time later): Seems that it is allready available in the web shop – wooohooo!

Edit (2008/08/13): Guess what? I called Dell today to order the laptop. When we walked through the setup page over the phone and came to the Display section, there was no configuration with 1920×1200 available. After consulting one of his colleagues, the sales guy told me that I probably have to wait at least A COUPLE OF MONTHS before it is available.
This is outrageous – who wants a top-of-the-line laptop in Q3/2008 that does 1280×800 or 1440×900 @ 15.4″ !? I currently have an old Dell Latitude D610 – that is a couple of generations old – guess what? It sports a 1400×1050 resolution…

When Dell hopefully releases the E-series this month, I will order a Latitude E6500 which will be the successor to the D830 model. It sports an eSATA port, GPS, DisplayPort, 1920×1200 WLED Display and is capable of managing 8GB of RAM.

I’m not sure yet if I’m going to order a new 24″ or the 27″ monitor yet, it may be that the 24″ is large enough for my desk (I have 2x 19″ Eizo doing 1280×1024 on it now).
