I definitely prefer Woocommerce to some of the other e-commerce platforms I have tried. I think it is awesome that it will be an integrated feature of WP in the near future.

I have to wonder as other posters have...if Automattic acquired Woothemes as well, can we hope that the visual style of the core themes packaged with WordPress will evolve as well? I'd like to see the default theme packaged with demo content as well, more like a high quality ThemeForest theme or Squarespace. As a developer, I've stood by WordPress but I worry that more stylish platforms (Squarespace, etc.) will start to pull people away from the open source community that makes WordPress so awesome.
