If you were holding off on the Honeycomb port for Nook Color because some pretty major features like sound and SD card storage weren't working, then it might be time to start downloading.  The SD card image (from developer deeper-blue) has been updated after only a day to take care of both of those issues.

At this point, the most glaring omission is root access, but considering we've gone from Google releasing their Honeycomb SDK preview to having a ROM that's pretty much ready for daily use in less than a week is quite a testament to this mysterious developer from Chicago.

Head on over to our How-To thread in the forums for the download and all the details--then follow along at home on our live blog of Google's "introduction" to Honeycomb today.  [xda-developers]
