High power consumption at 5V
Non-consistent interrupt response time (can be a problem with timer
ints)
EEPROM can get corrupted in brownout
Lower output drive than PICs
Inconsistent skip/branck instructions (some times you use skips,
sometimes you use branches, and they can only branch +/-128 bytes,
leading to spaghetti code...)
No immediate XOR
Will not wake from sleep on an edge (needs input held til CPU wakes
up)
