FWIW Ledger Nano X is finally shipping.

I received my pre-order on Friday. 

It arrived with a low battery warning.  I left it plugged into my computer's USB port for a few hours before the low battery warning went away.

I restored mine with the my Nano S recovery phrase.  Worked like a charm.

Used Ledger Live to add another coin group that would not fit on my Nano S.  Moved the coins from Coinomi to Ledger X.  Worked as expected.

Overall I am very pleased.
