Any tablet with a fairly current cpu that runs a web browser, a 10" tablet is fine. Alternatively a smartphone or a spare laptop?

@vinnn's correct if you are asking about a remote device but I'm wondering if you mean specifically a touchscreen display that attaches to the RPi and serves as moOde's local display. If so, then I'd suggest you stick with the official Raspberry Pi 7" touchscreen display. It looks great visually, performs very well as a touchscreen, is compatible with the RPi electronically, and is the "reference" design for moOde's local display function. Anything bigger and you have wasted screen space; anything smaller and you may find yourself squinting at the screen. The Raspberry Pi Touchscreen uses the DSI interface. I suggest you look at assembly and connection guides available online before you buy so you'll know what to expect. An HDMI display can also be pressed into service but it's hard to find a small one at a decent price. For another purpose I bought a bare 3.5" HDMI LCD touchscreen display. I've tried it with moOde. It works ok but the visual quality is noticeably worse than the official RPi display and IMHO the moOdeUI is too small in it to be usable in a bookshelf display. Regards, Kent

Sorry I was not clear. Yes, the touch screen that attaches to the rpi.
Thanks for the great info, helps a lot. :-) I looked at the photos. So the RPI will mount on the back of the official touch screen? No issues with the DAC hat on it? I have not checked yet. I’m using rpi4, not sure if it work with the rpi4 connection wise?

Yes, the RPi mounts on the back unless you cobble together some other arrangement (which might require a longer DSI flat cable). This doesn't interfere with adding an I2S DAC HAT on top of the RPi. (E.g., from front to back the full stack is the screen, then the screen control board, then the RPi, then the DAC.) The Touchscreen display should work fine with an RPi4B ... BUT ... notice that there are two ways to feed +5V to the screen.
Recently, I bought a SmartPi Touch 2 case to house the screen and an RPi3B+, along with the optional, extra deep back to accommodate an I2S DAC. I did this after seeing a post from new_bloke and exchanging PMs with him. I'm quite happy with this case. Right now I'm using it with a USB DAC. At some point I'll want to modify the back as new_bloke did to accommodate RCA connectors for an I2S DAC HAT so I can have a neat finished appearance. Why did I decide to use an RPi3B+ here when I have RPi4Bs in hand too?

This extender..? https://www.amazon.com/Electop-Extension...B07SV5ZFW4 My experience with the touchscreen was that it really benefited from a separate supply..or rather the Pi did. Unless the Pi supply is very beefy the screen would display the low power lightning bolt when using other USB peripherals. Of course, this could be improved using a powered USB hub but that sort of defeats the purpose of a small compact case without too many trailing wires. bob

That adapter cable is sorta what I had in mind but, zowie, 48cm? I wonder if this isn't a problem both for read/write speed and for EMI, but that's just me.

Pimoroni have this.. https://shop.pimoroni.com/products/micro...sion-cable or https://www.tindie.com/products/TEMProdu...sion-cord/ even a solid with sniffer.. https://www.ebay.com/itm/micro-SD-card-s...2647257537

Late breaking news:
I discovered that just yesterday, almost a year after the release of the model 4, the Raspberry Pi Foundation released a beta version of a new RPi4B eeprom which, among other things, enables USB Mass Storage Device (MSD) booting. From the posts I'm seeing on the RPFoundation forum, there's bugs to be worked out, but it shouldn't be long before this moves to general release. That will be sweet. We'll be able to boot and run from a USB3.0 device, which should translate to much better performance. The need for a uSD extender cable may be overcome by events. @DRONE7: Your Google-Fu is strong!
