I currently have an R4 and plan on switching due to that ominous message about the update which may or may not brick your DS. (I have a legit one by the way, just wanted to pass it down to my girlfriend who has a fake one). I love(d) my R4 because it was easy to use, especially with the spring loader thing, where I can update my SD card without having to remove the entire cartridge. Does the CycloDS have this feature? If my description isn't clear enough, I'm talking about the slot where you put in your SD card and much like putting a cartridge into a DS, you can press it and have it pop out for you.
