It's totally misleading that Ledger writes on their websites how Nano S is supporting 1100+ coins and app to 6 apps installed on your device, but in reality you can't install more than 2 or 3 apps.
Don't laugh, please.. 
When I read something like this I always thought it supported e.g. 1100 coins contemporaneously. LOL epic fail, when you advertise like this and the customer can only realistically use less than 10 coins at any given time... It's not like SPI flash is expensive, and it wasn't in 2017 either.Just an example:

NOR Flash 256Mb HyperRAM x8, 200MHz, Ind temp, 1.8V
It's 3€ for 32MB if I understand correctly (and you order 500 units).
