The DSi browser was also actually good. I preferred it to the 3DS browser, by a huge margin.
I actually preferred the DSi's web browser to the browser on my iPod Touch, because the DSi's dual screens were utilized in a clever way that made it easier to view websites formatted for desktops. (Mobiile-optimized websites mostly weren't a thing yet.)
By contrast, the browser on the original DS was a barely usable nightmare. I'm sure the developers did what they could with the limited hardware available, but the result ran extremely slowly.
