I'm doing some research with WordPress, boostrap and wocommerce and teh .Net OSS Umbraco for a prospective client and I must say the ease of use is fantastic and both I and client were very very impressed. Until she asked to see the Shop product list and whole checkout process. FAIL. FAIL FAIL. When I enable the WooCommerce twitter bootstrap plugin, the layout of the Product list breaks badly. The checkout pages are terrible too and are not usable in any small width devices.
