jayderyu - The browser is decent. It's not at all C2-worthy. But it is certainly good enough to browse most web sites - though my access to my the internet is not regular and I have my laptop, so I don't use my 3DS browser. It takes some getting used to browsing via a dual screen, but it's not difficult to use. The tedious part is tapping in every character for a web address or a message. LOL But if it's all you got, it's functional, definitely.
Ashley - Loading it on my 3DS, ScirraMark doesn't even recognize it, so it seems. It says:
Your browser scores ? out of ? (?)
You are using: Mozilla/5.0 (Nintendo 3DS; U; ;en) Version/1.7552.US
Whiteclass - It definitely doesn't compare to a computer. But it's functional. :)
