<script src="http://www.google.com/jsapi" type="text/javascript"></script>That code loads jquery and jqueryui. I don't have to keep them on my server. I don't have to cache them. It uses the compressed version for production and the uncompressed version in development. Best of all, the user very well might already have that file cached in their browser.
<script type="text/javascript">
<% extras = RAILS_ENV == "development" ? "{ uncompressed: true }": "{}" %>

google.load("jqueryui", "1.7.2", <%= extras %>);

{% if debug %}
local jquery
{% else %}
google jqury
{% endif %}
This is nice for debugging and limited connectivity when developing.
Good tip! I hadn't thought about limited connectivity. That's a killer.
