In addition, for those who have been modified their devices such as rooted and with custom recovery from 4.1.1 might take extra precautions before installing any 4.2.1 OTA update. If you're Transformer Pad currently runs with CWM recovery just be aware that ASUS has implemented their latest 4.2 firmware with a newboot loader that seems to have changed the type of partitions it wants to use.
There are certain reports the risk to brick the device if loaded with wrong combination of custom recovery.
For now, the only recovery that is safe to work with latest 4.2.1 OTA update is TWRP 2.4.4.0.
Head over to XDA forums for more info about this issue.
