10.3.9 Bad for Business?

Inside Microsoft seems to think that the recent release of OS X 10.3.9 could negatively impact sales of 10.4 for Apple. Their reasoning is that people won't pay for an upgrade when they just received one for free mere days before a major update of the OS comes out.

This makes little to no sense to me. Tiger adds over 200 features to OS X (some bigger than others) while 10.3.9 was a bug fix/security update (though it did include Safari 1.3). Suggesting that Apple, or any other software company, should stop supporting the previous version of a piece of software is ridiculous. I am certain that a large part of TUAW readers will not be upgrading immediately, and they wouldn't want to be left out in the cold without Apple tech support.
