I agree that brands are overrated (not with their complete irrelevance), but the Google argument doesn't prove anything. There is a huge difference in people's willingness to try a new search engine, compared to many other applications. Particularly when it comes to sites that deal with your money. That makes people conservative and want something recognizable.

Sure people were willing to try new search engines... until Google came along and built a better one.

Point is, branding takes a back seat to product quality, and the companies in question were clearly leagues apart in terms of quality. If they were of a similar quality, or if instead of "Wesabe" it was called "xXxVirus39" you would have a point. But that's not the case, so you've got your work cut out for you if you want to make a convincing argument that the brand played a relatively significant role here.
