I've seen the Toshiba screen in person. I have not seen the 5670 screen, but I have seen the Dell 8500 WUXGA. I can safely say the Toshiba screen is leaps and bounds better than the Dell. I tested the Toshiba's viewing angles and I could see it from all angles. The display does have a glass look to it, so it has reflections when looking from an angle, but thats no different than a CRT, and certainly wasnt distracting. I actually had the salesman take the laptop off the secured holster and carry it over to the CRT's and flat panels and hold them up side by side. The Toshiba screen had them all beat. There was 1 CRT in the store that had the same quality, but thats it.
I still want a Sager, but I want a Sager with this type of screen. I truly never would've thought that a screen could sway my decision so much, but I have seen the light my friends and now there is no turning back. I am just hoping that Sager gets this screen or else makes an announcement that they will sometime in the next 4-6 weeks.
