I have to say that I am really disappointed in B&N. Shortly after I found that loophole, I got a few hints from B&N people that it was probably part of an intentional design. It let the few who wanted to bother with finding apps elsewhere install the apps while not affecting the many who didn't care. Of course, these were the same sources that said the Nook Color would be getting the same loophole (it didn't), so clearly I shouldn't be listening to them.
When I announced that I was returning my Nook Tablet I got into a long an interesting discussion over whether I should have kept the NT and hacked it. A couple readers that I should keep it because it was hackable and thus B&N's restrictions could be bypassed. I returned it because I didnt want to have anything to do with B&N's walled garden, and I didn't want to fight with B&N over who owned the tablet.
Well, today B&N showed that they actually are fighting for control of your tablet. My post wasn't hyperbole; it voiced a real concern. As annoyed as I am with B&N, I'm also a little pleased to have been proven right.
This is going to end up being a major strike against the Nook Tablet. Why buy a device that you have to root before its really useful when you can get the KF and have more functionality for a much lower price? Sure, the KF has some software issues and Amazon has even blocked some reading apps, but at least with Amazon you know you won't need their permission to install apps.
In any case, if you're annoyed by this update, you can make your feelings known by returning the Nook Tablet. Thanks to B&N's generous returns policy, you have until 31 January 2012 to do so.
