I was just pondering getting his book, but then I read the comments here and reconsidered. Is it worth reading? Obviously you won't get a 4-hour work week, but is there anything of value in it?
There are also a lot of good stories about taking mini-retirements regularly rather than saving up for one large one and ways you can make it happen by convincing your boss to let you work remotely or by quitting, so it's not just about outsourcing.
It's worth a quick speed read in the bookstore, but I wouldn't buy it.
For US folk, I've got two other copies of his book, one of the original release and then a copy of the updated ones from last year. Claim it here and then send me an email with your address and I'll send them out.
