Well by 2008 we'd had consumer-grade 64-bit CPUs for 5 years and technically had had 64-bit Windows for 3, but it was a huge mess. There was little upside to using 64-bit Windows in 2008 and 64-bit computing had been hyped up pretty hard for years. You can easily see how one might think that it's not worth the effort in the personal computer space.
I feel like it finally reached a turning point in 2009 and became useful in the early to mid 2010s. 2009 gave us the first GOOD 64-bit Windows version with mass adoption, and in the 2010s we started getting 64-bit software (2010 for Photoshop, 2014 for Chrome, 2015 for Firefox).
It was different for Linux and servers in particular of course, where a lot of open source stuff had official 64-bit builds in the early 00s already (2003 for Apache for an example).
