Why are so many reviews comparing the dashboard to Palm's cards? Based on the screenshots I've seen, they're not alike at all, except that both have live previews.

And saying that they were "popularized by webOS" is a bit disingenuous since it launched less than half a year before the N900. Both are devices of the same generation, and I'm sure Nokia knew what they were going to do before the Pre launched. (Plus, the N900 is going to sell better, if we go by the strict meaning of "popularize".)
