Which ones of those would be worth buying?

The one you're actually going to read.

P.S. They have this "sale" once a month and the iPhone version of these books is also half the price.

(O'Reilly also provides instructions on how to get to the actual "book" out of the iPhone app:

It still amazes me that Amazon bought Stanza (which powers O'Reilly books on iOS). Stanza's still going strong though.
