As previously stated i'm not a big fan of books, not necessarily due to their inaccuracies at times or because i know that subject well enough to not have to have a book on it, but purely because i don't like having to carry more than i need to around with me as i spend a lot of time travelling.

I can't discount books like others have said purely on their inaccuracies because not everyone is perfect and even microsoft get it wrong - take BOL as an example, there's been many a time when they've got it wrong and later changed what was printed.

The only book i have bought recently is Glenn Berry's SQL Server Hardware and so far a lot of it is confirmation of what i already knew but i have leant a few things, even just simple things like what model numbers of the processor families actually mean, for me this has made it worth the £13 i paid for it.
