Right now, the Kobo Repairability page is a placeholder, but what's interesting is that they're announcing a partnership with iFixit to sell repair kits. iFixit makes good repair kits. I can vouch for their quality, but I imagine that with a bit of ingenuity and spare tools lying around, you can follow along iFixit's repair guides with or without said repair kits for true DIY.

It seems that repairability will only "be possible for Kobo Libra Colour, Kobo Clara Colour and Kobo Clara BW".
I wonder about the warranty, though. Usually warranties are voided the moment a user cracks open their device. Will Kobo allow self-repair AND intact warranties if you use official repair kits? What do you think? (It's probably NOT very likely. haha)
