To be fair, they state that they've changed their opinion on the repairability, and why, in the actual teardown:
Repair score: 2 out of 10
While the new iPad's design is essentially the same as the iPad 2, which we gave a repairability score of 4, we've learned a lot about the design since then. We've spent the last year trying to repair the iPad 2 with mixed success. We are awarding the new iPad an abysmal 2 out of 10, and retroactively dropping the repairability score of the iPad 2 to a 2 as well. The adhesive on the front is extremely difficult to remove without damaging the glass, making repair and end-of-life recycling very difficult.
That said, we were able to disassemble this iPad without breaking the glass - something that we did not accomplish with our iPad 2 teardown. A year of practice has made us proficient, but schools deploying the iPad for their students are going to be in for a lot of repair technician training.
The iPad is repairable, just extremely difficult. We've written a repair manual for the iPad 2 here, and repairing the new iPad will be very similar.
