Am I the only one who can only see "Magneto" whenever I see the new system's name?

Anyway, it looks nice (I really love the Ajax usage) but as daniel mentioned, it's fine if you just want a store. But as the reaction article posted above sort of implies, if you need a site that's more than just a store it's best to stick with the code that was meant for your CMS and not try to bridge them. (I was about to do that before I stumped upon Drupal last year).

But yeah if it's just a store you need, Magneto ... er, Magento .. looks like it'll do the job.
