Thank you so much, great info! I just ordered the Nano S and selected the express shipping and they said it's come in a couple of days. So I'll probably keep the crypto in Kraken until that. One less place to pay fees and one less things to study and to make a mistake in 
I'll try to read super carefully how to transfer the cryptos from Kraken to the Nano S (and create folders etc. first). If there's an easy mistake you guys are aware I would naturally like to hear it so I can be even more careful. I'll transfer a small amount first to make sure it comes as expected. One page also suggested trying the backup option before you put any money to see one can make it work correctly. I don't know if this is a good idea or if something could go wrong because of it.
