I don't know the answer to your "per person or household" question (my guess: per person).

As for any big downside -- none other than the 10K$/year limit. And having yet another account to watch and manage, though in some other thread somewhere someone says you can get them through your brokerage account, e.g. Fidelity, but that conflicts with something else I've read. They might have been talking about an inflation-protected bond fund which is different in a number of ways.

Edited to add: #1 in that thread isn't quite true. You can cash them after one year. But if you cash them before five years, you lose the previous three months of interest. (For example, if you cash an I bond after 18 months, you get the first 15 months of interest.) -- Source: https://www.treasurydirect.gov/indiv/research/indepth/ibonds/res_ibonds.htm
