The DSi browser was also actually good. I preferred it (by a mile) to the 3DS browser. Actually, I liked it more than the browser on my iPod Touch, because it used the dual screens to make it easier to browse websites formatted for desktops. (Responsive design wasn't a thing yet).

The original DS browser, by contrast, was an unbelievably slow nightmare. I'm sure they did what they could with the hardware that was available. But the result was barely usable.
