[Moto Z2 Force Accessories] apocalypse_bg:
I think a lot of the original Mods that they showed off as concepts (the presentation in India I believe) - example tablet dock, 4 SIM card mod

+ the rumored mods that had some pictures leaked like the 2nd compute mod (keyboard with ports + the phone as mousepad), really good camera mod with interchangeable lenses (or just a better sensor/optics like one of those entry level digital cameras which still blow mobile cameras when not counting post processing and not the ****ty Hasselblad mod which probably half of it's price is the brand license), the other 2 mods that got pictured (another compute and TV mod) were really good ideas, but the problem with all the mods (except when they were on inventory sale-off) was that the pricing was prohibitive for the average user, which hampered the mass adaptation of the Z phones and the mods respectively.

The only 3rd party mod that attempt to do something failed due to lack of components and support from Motorola (the keyboard mod, that would've been a nice tribute to the Milestone(Droid) and something without alternative until recently in Android world).

From my side, I would have to agree with a lot of the previous comments:

- Some kind of Nightstand dock with intelligent charging for the phone prolong the battery life + custom screensaver, an extra slot for charging a mod and maybe some speakers

- Better gamepad, ergonomically and with extra battery - I don't know whether it's just me, but I find the current one rather uncomfortable for prolonged use (more than 30-40 minutes).

- The edge mod, despite being a scam was an good idea, since Motorola doesn't have a ****ing notification light

- Keyboard qwerty mod ala old MIlestones/Droid like the one that failed on Indiegogo

- Something with an IR blaster - I find it odd that besides the old Notes, only some of the Chinese vendors have em' and I find it to be super useful, since the phone is more often with me than searching for the remote

- DeX style compute mod with full blown Linux - Big screen android sucks due the lack of optimised apps for that (and the mouse and keyboard support is close to non-existent in most apps) - I'm currently using the developer mod (since it has a SlimPort for video out) for that, but it's rather finicky.

just to comment on some mentioned ideas

- FLIR is cool, but limited use, expensive and they've got a dedicated USB-C one (which brings the problem with the mods - most of em you can get as universal devices for everything, not only a single series of phone)

- I believe greybus supports more than 1 device, whether you can actually do that with Moto Z's architecture is another thing

- There would be a 5G, with stated support at least for the Z3, whether it would support other Z series is questionable. But seems lame to me, considering that 5G is a huge hype with very little practical usage (maybe when the tech matures, but I don't see a use case for it on a mobile phone, unless we are discussing huge file transfers). And the mod is half a phone already (having the X50 modem with the Snapdragon 855), which is super pointless, unless you can utilise the second CPU (which can't happen due to to the way Mods connect through MuC) for usage in Android.
