Just as an fyi, you can use all of the wallets you need on the Nano S without worrying about space. You just can't have them all on there at the same time.

For instance, let's say you're hardly ever going to be transferring NEO anywhere and you want to have the ETH wallet on there most of the time. You can actually install the NEO wallet, add your coins, then delete the NEO wallet from the Nano S and add the ETH wallet and use it.

Then whenever you need to get to your NEO you can just delete your ETH wallet from the Nano and reinstall the NEO wallet and all your coins will still be there. It's definitely a little inconvenient, but still nice that it's an option.

I recommend you give it a try with a small amount of coins first and you'll see what I'm talking about. I was worried about running out of space and learned this was an option. I tested it myself to make sure and it worked for me.
