This computer I would have liked at times of my studies! Then I would certainly have taken the time to me deeply familiarize myself by 'trial and error' in the computer and its very getting used to the surface. Lack manual or even a help menu is no other way than fiddle until you have the operation under control. Too bad! The design is inconsistent and difficult to incorporate and the daily operation even more. But who undergoes the effort is rewarded with a functional richness that has no equal. For daily use, I'll stay with another machine which corresponds approximately to a scientific calculator HP. For special cases but is this app on my phone, also because of the nice additional functions as a currency calculator and unit conversions.
