I've found it quite hard to find decent hardware with both the input capability needed for wakeword and audio capture at a distance, whilst also having decent speaker quality for music playback.

I started using the Box-3 with heywillow which did amazing input and processing using ML on my GPU, but the speaker is aweful. I build a speaker of my own using a raspberry pi Z2W, dac and some speakers in a 3d printed enclosure I designed, and added a shim to the server so that responses came from my speaker rather than the cheap/tiny speaker in the box-3. I'll likely do the same now with the Voice PE, but I'm hoping that the grove connector can be used to plonk it on top of a higher quality speaker unit and make it into a proper music player too.

As soon as I have it in my hands, I intend to get straight to work looking at a way to modify my speaker design to become an addon "module" for the PE.

100%. For a lot of users that have WAF and time available to contend with, this is a steal.

Bear in mind that a $50 google home or Alexa mini(?) is always going to be whatever google deem it to be. This is an open device which can be whatever you want it to be. That’s a lot of value in my eyes.

In many cases the issue isn't the microphone but the horrid amount of reflections that the sound produces before reaching it. A quite good microphone can be built using cheap, yet very clean, capsules like the AOM-5024L-HD-F-R (80 dB s/n) which is ~$3 at Mouser, but room acoustics is a lot more important and also a real pain in the ass when also not a bank account drain if done professionally, although usually carpets, wood furniture, curtains to cover glass and sound panels on concrete walls can be more than enough.
