I finally gave in last week and bought a Nook Tablet. After spending all of 10 minutes checking out the stock interface, I rooted it using Snowball-mod. It strips the tablet down pretty close to the barebones Android system, and provides root-level access. Having the ability to ssh both from and to my mobile device is awesome. It makes me feel like I’m carrying a tiny Linux box around in my pocket (which is pretty accurate).
The folks over at XDA-Developers (where the Snowball-mod instructions are located) are pretty amazing. You should check out the site if you are interested in hacking on mobile devices.
Even with the stripped down Nook, I’ll be installing CyanogenMod as soon as it is available for the Nook Tab. I’ve been running it on my phones for a couple of years, and I’m quite happy with it.
