Apparently, the MV is supposed to help lots with that.
No it does not, actually the non-MV SXGA+ screen (which I have on my x61t) is better outdoors. Still not usable under sunlight, even difficult in the shadow on a bright day.
I would be curious to see how the two screens compare because tabook says they are both outdoor worthy. Checkout this exerpt from tabook that talks about the X61T displays...
12.1" (307mm) SXGA+ (1400x1050) color, 190 nits, 4:3, 500:1, 170° viewing, direct bonding panel (SuperView) for improved outdoor viewability
12.1" (307mm) XGA (1024x768) TFT color, 4:3, 150 nits, 170° viewing / MultiView (indoor/outdoor), MultiTouch (touchscreen via ﬁ nger and pen)
Super Wide Angle FFS / anti-reﬂ ective and anti-glare protective coatings / write on screen with standard digitizer pen / pen holder in front base / rotate and swivel hinge in middle bottom of display for tablet mode (portrait or landscape) or picture frame mode (keyboard faces away from user) / buttons on display bottom (power, lock, reboot, rotation, utility, Esc, NavDial/enter)
From my personal experience the MV/MT screen is usable outside in the sunlight whereas my X61s really isn't. I'll try to take some pics later today or tomorrow (I'm in the Sunshine state so it shouldn't be hard to find a sunny day to take pics). Pibach if you could take some pics of your SXGA screen outside and post them that would be cool too because then we could see all three. It would be nice to see if the screen brightness between the SXGA and MV/MT is a big difference when being used outside.
