Exactly.

Apple adds features based on what users seem to need, not what programmers want (Google) or programmers want to work on (Mozilla).

It should also be noted that Safari's accessibility support is head and shoulders above anything (including IE with dedicated third-party extensions -- our blind accessibility guy who has access to every accessible technology under the sun simply uses Apple devices at home).

Wake me up when IE is open source, Google gives flying f* about accessibility, and Firefox is better than a distant second.
