Microsoft announcement about being able to use flash drives with you Xbox is way over due. Starting tomorrow, April 6th, you can use up to two 16g flash drives as memory for anything on your xbox. Before this the only way to take your gamercard to a friends house or game saves was Microsoft's way over priced memory.
While this is a good start hopefully it will carry over into hard drives also. With more and more DLC and need for extra hard drive space, you would think Microsoft would eventually have to let you use your own hard drive. I guess time will only tell.
