Summary: The software is stupendous, and would earn 5 stars on its own. Unfortunately for today's internet the DS just doesn't have the power you need. No flash is liveable, but the render times are crippling. If all you want to do is read the news and check your email this may be worth it. I switched my nytimes subscription to weekends only, and just read the weekday news on the ds now. Unfortunately that's about the limit of this device's usefulness.
Summary: The Nintendo DS Browser functionality is far too limited to be of any real, fun use. The greatest problem I have is the load speed - even when you're connected to a very good hotspot and have image-loading turned off, it'll still take 10 to 20 times longer to load a page than say, a computer. Perhaps this is an unfair assessment, considering the DS *is* a game system, but for that price tag you expect a bit more.
Summary: If so, be prepared to do a bit of tap, tap, tapping of the fingers. I love my DS, and around 5 years ago, this would have been a decent mobile browser. But today even the most minor websites have lots of data and images to load, all of which will bring your surfing experience to a near standstill. I don't think this is the result of too-high expectations, either.
