Overall "ranking" and verdict	Pocket: poor; Concise: better but still much worse than most other dictionaries	Definitely better than the Pocket PC Oxford implementations; worse than American Heritage Dictionary	One of the best	Very good / Good	CALD: Very good; tons of examples. A: it may be weaker (for example, the "charm" hits are very weak, compared to say CALD; the "good" hits are very good, on the other hand)	Good; not as many examples as in CALD	Not as good as WordNet - the latter has better connections	Not very good; really outdated and old-fashioned. Even WordNet is much better.	Online and full version is pretty good and worth checking out; definitely not as good as Cambridge's CALD though. MSReader version is FAR worse (it completely lacks example sentences from the "real" Encarta version, only lists (all) the main meanings): 1 2
