Some may remember the questions raised when Halo was first announced for the Xbox, specifically with regards to how chatting would work in Internet play. This, of course, turned out to be a non-issue when Halo shipped without any officially supported Internet play.
However, at the time, there were those of the opinion that any shooter was best played with a mouse and a keyboard, and that having a keyboard gave the added advantage of allowing text chat.
Now that Xbox Live is out with voice chat, texting seems unnecessary. And most will admit that although different from the mouse and keyboard, the Xbox controller is more than serviceable for playing Halo.
However, that didn't stop Sega from doing what many said could not, should not, would not be done-- the production and sale of a dongle that would undo the incompatibility-creating USB dongle that Microsoft made for the Xbox to prevent you from plugging USB peripherals into what is, essentially, a USB port.
That is to say, they are selling a USB keyboard adapter for use with Phantasy Star Online, which was noted today at Penny Arcade, which also has a bit of a review of the Xbox version of PSO.
Enjoy.
