That brings up another question. According to Amazon (confirmed by phone), the six device limit is for simultaneous use of devices. However,
others have reported that the limit is being applied to number of devices/serial numbers that have appeared on one's account, regardless of returns or exchanges.
Apparently this issue has been tested with individuals who have gone through multiple returns/exchanges and have exceeded six devices.
It would be nice to know if devices/serial numbers are permanently attached to one's account. This could be a real headache in the future given the number of upgrades, exchanges and any additional authorization of new hardware from other manufacturers (i.e., iPhone). Seems illogical to me.
