I wondered about that… At Liberty University, we have not had any real electronic failures with our 2800+ Aruba APs. The early AP125s (2008) had a plastic casing issue that broke due to heat and we had some physical damage issues (water & broken antennas) that were beyond the vendor control.
Overall, we are extremely pleased with the AP performance.
