If you're in the market for a NookColor then you might want to keep an eye out for the latest production run. According to Engadget, Barnes & Noble have screwed around with the internal storage. If you find a NC with a little blue dot on the box, it means that you're holding a buggered tablet. B&N have cut the user accessible storage to only 1GB. They've decided to reserve the other 4GB for content you bought from them.
I suppose it doesn't matter much; if you hack it and install CM7 (or some other firmware) that restriction won't mean diddly. But it's the principle of the thing that bothers me. Barnes & Noble think that they should have more control over your property than you.
