You mean the MX Duo? Same as mine... works fine here, but i only use it occasionally, so not sure of any issues in long term. 

XBL Spring Dash Update at Least 24 Hours Off
A little longer to wait for chatting with MSN buddies.
By Dan Dormer, 05/08/2007

To ease gamer anxiety, Major Nelson announced late last night that the spring dashboard update is "not being released in the next 24-hours." This update adds chat functionality, a new "marketplace" blade, tweaked background downloading, a specific achievement unlocked display and establishes regional content locks for Video Marketplace goods.The official press release stated the update would be available "the week of May 7," so Microsoft still has time before gamers grow completely restless. While 360 owners wait, they can check out 2 new videos on XBL showing the ins-and-outs of the new features.

If you're having trouble finding them, here's a road map: demos and game videos --> game trailers --> gaming community --> behind the scenes --> game trailers --> voila!

Ok, we're getting closer. I just learned that the May '07 dashboard release is set to be released just a few hours from now. To be more specific, the LIVE Operations team expects to start rolling out the update after 0200 PT tomorrow morning. I'll make another post when the team start the roll out.

The PR team has issued an alert, so it must be official...right?

For all those just joining us and worried that our slow internet connection might brick ur box during the update.

Don't worry.

The update is done in 2 phase
- Downloading
- Updating

First phase it'll say "Update is being downloading, don't turn off bla bla bla.."
If something bad happens at this point of time.. you'll be ok.

2nd phase it'll say "Applying update, don't turn off bla bla bla" at this point of time if anything bad happens YOU ARE F********

So try not to do it in the middle of a rainstorm!
