@DG how so? Most likely it will be superseded by the next Xbox so unless MS are going to allow some sort of upgrade path (not likely) or make the X the base for next gen (possible given the idea of a "family" of devices) getting an X to future proof does not seem like a good idea.
I've noticed that after scrolling down in the chatbox sidebar, it will automatically snap back to the top after a short period. It makes reading posts that are lower down a bit frustrating. Delay to reset ranges from 7 to 14 Mississippis but doesn't happen when clicking inside the chat textbox first before scrolling down.
