Have the device only a few days and a lot installed, just compute-intensive facility work, and appreciate the battery (the battery has 38 Wh) CA has held for 8 hours. Rough 10% battery consumption per hour. In normal use, I think are already 10 or more hours in there if you do not constantly surfing on very CPU-heavy Adobe Flash pages.
The device runs much smoother than I because of eMMC (HDTune measured maximum read rate of 99.6 MB / s Average over 90MB / s) would have expected nothing compared to my old netbook. (On winXP despite genuine SSD probably made no fun also because of the slow old N270 Atom Prozzi). The device boots thanks Win8.1 in about 10 seconds for Windows logon screen, amazingly, but it is quicker than my desktop with real SSD and Intel i5 quad-core (Which probably has 10 times the performance ...) just only Windows 7 ,
On the subject of bad browser performance or tougher side structure I can say:
When websites (then CPU utilization at about 60% at 1.6 to 1.8 GHz) will open the much Flash content have been going on the side structure admittedly a few seconds. Normal pages but are loaded very fast. Compared to my old netbook built in 2008 with Atom N270 (single core with HT) a significant improvement in every respect. Battery and display CPU much larger and much faster (according to benchmark multithreaded about 3x as fast as N270). It must be remembered that it is a trimmed on extreme power saving CPU is which of course no comparison to an Intel Core i5 or better flat.
Unfortunately, I have to move it until now, despite several attempts, not yet managed to boot a backup program to create a backup outside of Windows.
The exotic 32bit UEFI annoys me because something ... free to contact functioned proposals :-)
