You can also save product to see it later by checking the "Save for Later" link, which will open a layer with different saving options available. Clicking on the "Add to my tech product" link will add the desired product to your "Saved Tech Products" which is always available in the right menu, the add event is mixed with a nice javascript effect before seeing the product displayed in the same page.

It's possible also to rate the different products and share your opinion with others, the rating system is also using AJAX allow to save your rating in real time by clicking on the "save button" without reloading the page, and also display a small window when saving is done. I find it very well done especially that it avoid clicking on stars by mistake and showing unreal results. And after rating, you can close the window and the save button disappear.

Overall, I find it very web 2.0, especially with the change screen width feature. An excellent example showing some of the fonctionnalities we can implement with Y! UI. The only thing that I didn't like is the ~130Kb of Javascript and ~56Kb of CSS, everything else seems to be very well optimized.
