Informal writing style not my favourite but plenty of information, the bits from Arup are good, it's long enough to be useful without being too long to digest.
A handlful of gramatical and technical errors, but I would guess you can find the errata on the publishers website.
Lots of screenshots, though I found some irrelevant and a few "would like to see" shots absent.
A bit after-the-fact now that 11gR2 is out, but for the money this represents a cost effective way to disgest the 11gr1 new features without needing 500 reading hours.
