This.
And I get a 3-4MB page load. Definitely not fast, though.
Maybe it's a lottery as to whether you get the new one? Like Facebook does.
Speaking of Facebook, all the stuff that takes a long time to load is third party. Google and Facebook. I don't get why people still use their analytics, it's not wildly difficult to write your own, or get something that runs locally:
Has anyone ever genuinely bought a product because a friend Facebook liked it?
Both the systems and laptops links in the mobile nav bar don't work and TBH I think that the newsletter and testimonials only need to be on the home page as they take up too much room on the mobile site (i.e. makes it difficult to find help/info/service). There's still no way to filter what's in stock vs. what's on backorder as well, which makes sifting through things on sale a major pain.
Website page weight is a bit heavy as well, consider using srcset as the mobile version of the homepage doesn't need to be 8MB in size. Other than that, not too shabby.
Oh, I didn't check the mobile page, is it somehow twice the size of the regular?
