It's not always the best option.

As you've said, scripts run serially. What's more, they're run pretty much as soon as they're seen in the page...and they tend to tie up the browser while they're running, and keep it from working on loading stuff and rendering the page. Many times it's better to have scripts at the end of the page, for just that reason -- by the time they run, the user has something to look at, so the delay isn't as obvious.

Personally, i only put scripts in the head when other scripts in the page require them. Libraries and such. Scripts that actually do stuff while the page is loading, go into the body.
