It is often the small details that drive you crazy and make you go mad. Barriers you have to move aside to clear your way and make it walkable as usual.
This is particularly true for our daily used technical devices such as Mac or iPhone. Often you don't know how to tackle a problem to get it solved quickly and effectively. In situations like these, we are thankful for a helping hand - Someone who is on our side and who helps us with his knowledge and power.
