i have read that the new DSi has a built in web browser and more RAM, but does it have a flash player to play streaming videos from like youtube or stuff like that?
You can check out all the latest info on the DSi at my new site, http://www.mynewdsi.co.uk. To answer your question, there is no flash support on the DSi. But you are right about the extra RAM and free browser. Hope this helps
