http://operawatch.com/ They've announced the dates that the Opera Browser for the DS will be available. July 24th for Japan, and October 6th for Europe and the US. "The Opera browser for Nintendo DS will be sold as an optional DS card. Users simply insert the card into the Wi-Fi enabled Nintendo DS, connect to a network, and begin browsing on two screens."
The psp browser is kinda cool, you can save content whether it be psp compatible or not to the memory stick. extremley usefull if you ask me. But it was as slow as balls, the cache on that thing honestly was more like 100kb IF that. I would scroll a page for example with lots of html graphics, and when I got to the bottom (not a very big page) and went back to the top, it would have to reload the top page content again.
Opera DS sucks, got it today. Takes forever to load large sites. Handheld gaming device browsing is still ass.
