It's actually not bad. You don't need WiFi on a desktop*, so you can shave off $20-30 on that. Buy anything other than Asus and shave another $20-30. And you get a pretty good price. Not cheap overall, but great bang for what you're paying.
*most of the time. But even if you need it, chances are you already have a WiFi adapter, so you can still forego wireless on your new mobo.
Personally I treated WIFI module a MUST for every desktop machines I had, both work and gaming.
The WIFI part is a useful backup & diagnosis method when the LAN connection goes funcky.
The included Bluetooth is a necessary component for many gadgets , for example: Gamepads , multi device keyboard/mice.
Adaptors occupies additional USB ports /PCI-E slot, which is a huge waste
I would avoid any non-WIFI equipped motherboards unless I am building a server, which don't need any gadget connections, and has multiple LAN ports for monitoring /diagnosing.
