That was a good news that i think it really can help a lot for those who are using in fact because of the transaction increases day by day a wallet which is supported segwit that can help to save 35% of the fee paid..  
That i think its really help a lot for those who are honestly transacting high and low amount of bitcoin..
Hope also that in the future that there are also wallet that can merge the input without paying a fee because this is really a high problem when you are sending bitcoin to another wallet.. high input higher fee.
Ledger nano s is now much better than trezor that i think much safier than trezor that we heard some issue happen past few days ..

I was emptying my legacy account today to send all the coins to a segwit account.

I realised that all the inputs sent to the same addresses (on legacy account) were than sent as separate inputs (although from the same addresses) to the new address. I wonder is this normal behaviour? It increased a lot already high fees. It would make sense to me that one address would be one input.

Is that just bad implementation of the wallet?

Inputs =/= Addresses. Every amount you receive separately is a new input. This means that if you receive 1 payment per day for 1 whole week, you will have 7 inputs at the end of the week, increasing the size of your transaction.

Thank you for explanation. Much appreciated.

Wow, nice to see that Ledger is already pushing out Segwit support already. Hopefully we'll see support added to other wallets such as Electrum soon as well. The network fees are still crazy high so hopefully once enough people get migrated to segwit addresses, it can help lower these fees.
