Concerning the IPS display, might there be any difference between CB5-571 and C910? http://www.laptopmag.com pulls the panel into pieces writing:
QuoteAlthough the Chromebook 15's 1080p screen is plenty large, it doesn't offer a great picture. Watching movies and TV shows was underwhelming. When viewing the HD trailer for The Avengers Age of Ultron, Captain America's shield looked clear, but the blue sky and orange flames looked muted.
Viewing angles were fairly decent, with image quality degrading slightly when I moved beyond 45 degrees. Despite its anti-glare coating, the screen still reflected some overhead lights during a dark scene in the Avengers trailer, making it hard to see.
Notching 228 nits on our brightness meter, the Chromebook 15 is dimmer than the average mainstream laptop (251 nits) and the Toshiba Chromebook 2 (339 nits), but brighter than the Samsung Chromebook 2 (214 nits) and the HP Chromebook 14 (209 nits).
Based on our colorimeter readings, the Chromebook 15 can display just 58.1 percent of the sRGB color gamut. That's much lower than the average mainstream notebook's 82.8 percent, the HP Chromebook 14's 61 percent and the Toshiba Chromebook 2's impressive 98.5 percent. The Samsung Chromebook 2 notched a poorer 57 percent.
IMHO: Devastating!
