Doesn't the HD format in Bitcoin Core's wallet.dat avoid ever showing the seed for security purposes? (therefore you can't also enter any seeds)
What's the difference from the HD wallet to the non wallet? I still have the old wallet which doesn't have "HD" icon enabled...
Other than to not have the 100 keypair limit, does it provide any other advantages? (or disadvantages) compared to the old non HD wallet?
I believe the newer versions of "non-HD" wallets will actually run a keypool of 1000

Anyway, advantages of HD include only ever needing to take one backup... you do actually get the "master private key" if you dumpwallet, so theoretically, you could write that down and store it offline and then be able to recover your entire wallet by importing that into a compatible wallet.
However, in the limited testing that I did, with the "seed changes on password change" system... if you change the password (or set one)... the OLD master private key is not stored... only the addresses

Also, I guess having an HD wallet would make it easier to use your wallet from multiple locations and not need to worry about it generating different addresses? (assuming you don't change the encryption password!

) It probably makes creating "watching only" wallets easier too...
Whether or not you consider any of these advantageous is really dependent on your particular use cases.
