When it comes to pocket textbooks, i.e. abridged versions of their daddy books, there are three really. Churchills, Mini Kumar (Pocket Essentials of Clinical Medicine) or mini Davidson's.
Most people seem to buy mini Kumar, but as I loathe Kumar I bought the mini Davidson's as soon as it was published. This is a fine book, complementing the OHCM well in my opinion by making up for the lack of explanation that the OHCM suffers from. A colourful, well illustrated book using lots of pictures, drawings, tables, flowcharts which I enjoy. The text is broken up into small paragraphs at a handy A5 page size. This is so important, as being bulletpointed and broken up means I remember more! Broken up into systems.
Highlights include: A clinical examination one page summary the beginning of each system is very useful. Includes dermatology, clinical pharmacology and prescribing inc. antibiotic use, data interpretation guides e.g. radiological interpretation and labs as well as a Finals OSCE preparation segment at the rear. Handy quick reference lab values on front and rear. Anti bodilyfluids spill tortoiseshell cover. Pretty much everything you want!
Downsides: Lacking in detail in some areas, for example wanting more treatment protocols, more findings on xray/labs etc. Davidson's style is not to everyone's taste. The publishers I think got a little confused as they are marketing it as a ward book as well (hence spill cover) but it is far too big for a pocket/bag really.
