during the Sp3 conference, the guy mentioned some kind of tech on the SP3 that doesnt strain eyes, what is it? im not one who usually likes to have high brightness, mainly cause it will strain my eyes. if i have my phone screen set past 50% it strains my eyes. same with every other lcd screen i use. but i notice the Sp3 even at the default brightness setting out of the box at 50% actually doesnt put any strain on the eyes. it feels so nice on the eyes. i think this is because of the technology it uses. 1) what brightness do you like most? 2) is it me or does it seem that the sp3 is actually easier on the eyes when set at a higher brightness than normal compared to other tabs? 3) does the device look sharper when at high or low brightness? 3) how do i get the 9 hour battery life? someone here actually mentioned that you actually get more eye strain from the sp3 when its at a lower setting than a higher one, which makes no sense.
