I e-mailed Tom to ask for the update and below is the reply I received. I will reserve my comments, you judge by yourselves.
Try to do the right thing and sometimes it doesn't work. I never promised free updates when I began selling some of my books via download. Indeed, to do an update with this new process costs me real money: I pay per email/download. But I decided to try doing updates anyway, as I expected that to be a smooth process. I've now tried updating twice. The results have been extremely disappointing. Basically, so many of you are on vacation, forget to download within two weeks, didn't notice the download message because it ended up in your spam folder, and so on, that I now spend many hours each week manually handling these free updates. That's on top of the physical costs of providing them. Bottom line: it means other things don't get done, things that you probably want me to do (launch the new bythom site, write more reviews/books/articles, and more). Therefore, there will be no more free updates in the future. It's not a cost effective use of my time. That said, I've reset your link and you should receive an email to that effect shortly. However, don't forget to look in your Junk or Spam folder: I have no control over where your email system puts an automated email. Note that the link only goes to the email that you ordered from. -- Thom Hogan, writer/photographer author, Complete Guides to the Nikon cameras (25 and counting) author, 36 books on photography, programming, and computing
