A company that I have not heard of before, Datel, has announced a 4 gigabyte hard drive that is designed for the Xbox 360. Since it is USB, it can of course work with your computer too, but it has the colours of a stock Xbox 360, and while you can’t save your games on it, or anything, it could be a great little attachment for pictures and music. At around $135 US to preorder the device, people are wondering if it is really worth it.
I guess we will have to wait and see what public opinion says, though I wish it was a Microsoft product that allowed me to put my game saves and whatnot on it, like a giant memory card.
