[Q]: I bought these to help with what I've read, to get the Jawbone to fit better. These ear pieces were hard to get into the ear no matter what size I tried. For a wireless earpiece you want to be able to get it on and off your ear quick if you need to, and these prevent you from doing so.
[A]: Negative

[Q]: Cities Of The Red Night is one of the most enjoyable books I have read. The novel has different storys that as the novel progresses intertwine. The books presents situations that are unbelievable but because of Burroughs genius you are convinced of that they are happening in a world not too far from are own. I think he was trying to show the questionableness of what is presented to us as reality. This book also has some of the most vivid pictures and unforgetable lines that I have read. It is Burroughs masterpiece.
[A]: Positive

[Q]: An excellent scholarly book. Great detail and very in depth analysis. Inevitable conclusion is the impossibility of molding an economic system out of a moral philosophy, not just Islam. That is where the problem with traditional Islamic thought arises, for most of its adherents, Islam is not just a set of moral principles but a way of life, dictating every aspect of it. Unavoidably, there was much effort by Islamists to set up a distinct system of banking and economy based on pure Islamic traditions. Prof. Kuran delves into the history of these movements, but he does more than that, he puts all this in cultural and political context. At the end, he bravely expands more on the general failure of Islamic culture and tradition to bring wealth and prosperity to the masses that follow it. Writing is very formal, not the easiest read and surley apporpriate only for the truly intersted in the general topic, but it was well worth it for this reader.
