Great review! Make sure you update your Nano S to the latest firmware 1.4.1 though. I've literally just posted about this in my blog... The update allows you to store up to 18 wallets all at once (great news), and also provides an important security update. I highly recommend you do the firmware update now... even if you don't do the update now, i believe Ledger are enforcing everyone to update to the latest firmware by the 20th March (giving a two week grace period from today). Thanks :)
