I have an R4. I was just curious as to everyone's opinion on the DS browser. I am out of the house a lot and do not have a laptop, and there are two locations I spend time in where I could use the wifi to access the internet with it, but $30 is an awful lot... do you guys think the memory expansion will become very useful in Homebrew (such as QuakeDS) and do you think that possibility justifies the $30 price tag?
