The turn-around time between source releases and dev community releases seems to be shrinking more and more these days.  Just two days after Google released the Honeycomb SDK Preview, dev deeper-blue now has a (very early) port of it running on his Nook Color.

Originally describing it as a "zombie" without any touchscreen or hardware acceleration, he later reported that he has the touchscreen working and hopes to work on acceleration over the weekend.

While this won't be able to escalate into full-blown Honeycomb on the Nook until after Google releases the full source (presumably sometime after the release of the Motorola Xoom), this could be quite a treat for those itching for the buzz of Android 3.0.   [xda-developers]
