Indoors I have the display up on full so I am outdoors right now in the full sun. With all the comments around 200cdm etc I thought this would be impossible.
The display must be partially transreflective because it is quite visible with the full sun on it above and behind me. Even if I turn the brightness to zero with the sun above and behind me I can still just see this comment I'm writing...
With the sun in front and above, it is still ok but not as bright because the sun is not contributing and there is some minor glare from the shiny case/keyboard area.
Also 8 hours battery?? It's more like 4 hours. Minimum power usage on linux mint is about 8.8W with min brightness and not doing antything. Normal unintensive use is half to full screen brightness 10-12W. 52Wh/12 = 4.3h which is about right. HD Movies or processor intensive stuff push it closer to 15W.
Since you can upgrade it, I've put a 1tb hdd in the spare dock and use it for storage and upgraded to 8gb ram. Most of the time the hdd is off and using no power. I was surprised to find adding the ram did not increase power consumption significantly, I could not see a difference before and after.
One downside is using an external solar charger or 3rd party psu you need to put a 100k ohm resistor to the centre pin from +19v or nothing happens. Not happy but better than a digital signal! The only other downside is it isn't haswell.
I think HP has done really well. I've got the ultrabook I wanted with built in storage, 8gb ram, and all the ports you could ever want (except HDMI).
