The Express is sort of lost right now.
It's rather too big and clunky for a travel router in comparison to others (and more costly), too slow and feature crippled for a regular router, and even a bit behind in the AirPlay realmthere are tons of speakers, sound systems, etc that run directly off wifi or bluetooth now while the Express still uses a 3.5mm jack. And you can only configure it with Apple's proprietary software, at least until they EOL that utility and it becomes a brick like the older Expresses.
I hope they don't update the Express, and instead start all over. Or maybe it's just not a useful category for Apple given you can get about the same functionality for a fraction of the price from numerous other vendors.
