The browser on the Wii was amazing. I didn't use it all that often, but I was a big Opera fan back in the day, and it was amazing to see how well their engine scaled to all kinds of systems.
As far as I remember, there were even some games that supported the Wiimote natively? I don't remember if this was via Flash or Javascript, but there seems to be a library for the latter: https://github.com/ryanmcgrath/wii-js
I unfortunately never got to use the Nintendo DS version (the DS being WEP-only was a dealbreaker for me).
I bought the NDS version back in the day and let me tell you it was not worth the 40€ of my pocket money.
If only the Wii had supported 1080p or even 720p output, it could have been a great way to browse the web in your living room. Many companies have tried this, but none of them had the correct input device. I think this could have changed the overall direction of technology.
Unfortunately, at 640x480 everything was too small, even back then.
I remember using Orb on the Wii way back then for media streaming. Good times!
Yep, I remember a brief period of time where I would play Flash games on the Wii browser, I think there were indeed some that were explicitly made for the Wii browser. Fun times!
