Didn't know where to post this, but I thought here has the best chance of getting replies. I made the topic as wide as possible so that future hardware question can be asked too.
This might be dumb questions, and I will get interesting replies. (maybe?!

) but I'll ask anyway!
My Kindle Keyboard 3G screen is broken now and I've got a Kindle Touch... just wondering if their eink screen is exchangeable. I couldn't find their specification anywhere... If you could help, that would be awesome.
