I noticed this yesterday. I don't know why HTML would be to blame, as I've used web browsers on low power devices before and they can be very snappy.
One thing I noticed was that when attempting to switch between e.g. 'Offers', 'New' and 'Highlighted' or whatever the headings are, there's a large lag / hangup. It certainly doesn't feel like they're working on keeping it fluid and snappy. That might not be a priority, but I'm certainly put off browsing and buying when it's unpleasant to do so.
To be fair, it's worse on other consoles IME, and if I keep my browsing light, stay at the top of lists and don't get too impatient, it's okay.
