Especially when the whole point of Gruber's article is that nobody uses video calling because it's a confusing and complex mess, and when it isn't so (e.g. skype) it gets used, and when iPhone 4 comes out it will get used a lot more.
So let's compare-
Apple iPhone 4 - instantly popular with millions of people using the exact same make and model with the same software within a few months. Video calling baked in as a single button visible on every phonecall, advertised as a primary feature, designed for easy use.
Evo 4G - Phone with camera on the front. Not such a one-off instantly popular hit. Video calling not possible until specific apps heard of, downloaded and installed, configured, then still different and more hassle to use than a normal phonecall. Other features vary by app.
And only the truly antiApple could suggest that people are calling Apple's take "done" in any final sense as if nobody believes it will ever change ever.
