HTC may have put the Nexus 9 on a deep discount today, but that won’t help you much if you need to repair it. As they often do, iFixit has torn down the tablet, and proved how repairable it is. Or isn’t. An extremely low score suggests this is one you’ll need to take care of in a big way, discounted or not. Even the more routine fixes will require a great deal of skill, and likely expensive replacement parts.
