Apart from a couple of minor niggles (e,g, a question about AdWords Editor without any previous mention of the tool) this slim book covers the subject pretty well. The self test questions make you think and are helpful in learning the subject.
Fairly standard format (two communities with stereotyped characters). Completely unbelievable protagonists. Finished reading it feeling deeply depressed because a) the story is depressing anyway and b) I had expected much better characterization from JKR.
Purchased this for my wife who needs a device for e-mail and web. She likes a 'proper' keyboard, so a tablet was not an option. The price was good (I also paid less than currently shown) and it performs well. The only slight negative is Windows 8 and the dreadful new version of IE. However I installed Google Chrome and everything works.
