The Nook Color has apparently been pulled from store shelves, but only temporarily. The ereader is backordered at Best Buy, and the Barnes & Noble site says that the device is not shipping for two weeks. They gave no reason, but several outlets are reporting that Barnes & Noble wants to make the Nook Color hack proof.

You might remember that the Nook Color was rooted and new unofficial Android OS firmware was available to turn it into a full blown Android tablet. It’s possible that Barnes & Noble feels that custom firmware allows users to download competing e-reading apps like Kindle. But who is going to want it after they “fix” it?

Google and NVIDIA together faced their second setback together as a leak on Saturday revealed that Staples was pulling the ViewSonic gTablet from store shelves. The tablet is being pulled due to a “manufacturing defect” and its display area has been removed entirely.

Right now there’s no indication that the gTablet will ever return, and customers who are seeing this week’s flyer will be told that there’s no equivalent replacement. Also, neither Staples or Viewsonic has explained what the mystery flaw is or whether the gTablet would return later fixed.

The Archos 5 Internet Tablet has been available for just a couple of days, but now Amazon has stopped all orders for the 160GB hard drive-based Archos 5 device, placing the item “under review.”

Amazon says that “customers have told us there may be something wrong with our inventory of the item”. This is not good news for Archos. However, the 32GB flash-based version is still available for pre-order. Hopefully the issues, whatever they are, can be fixed quickly.
