My first reaction to the specs:
Pros:
+ USB 3: Very nice! Finally a pocket-sized, fast USB host.
+ Dual HDMI: Could be useful as a projector computer.
+ 1.5 GHz: Good, it might be fast enough for some real work.
+ Gigabit Ethernet: Excellent for those using it as a NAS.
+ USB-C for power: Not surprising, it's the standard now.
Cons:
- MicroHDMI: Incompatible with the 800x480 HDMI 3.5" screen [1]. Also different again to the MiniHDMI on the Pi Zero (will there be a new Pi Zero soon? Who knows.)
- Power consumption! They recommend a 15W power supply, which means I'm pretty sure this won't run on batteries.

- rs23296008n1 7y agoJust need a bigger battery. 15W is achievable. You'll add more weight obviously but you get the extras of the pi4. Tradeoff. As for the screen you pointed to, isn't an adapter available?
- agumonkey 7y agoalso, 15W is max power I suppose, how low can it go if you configure and use it for small tasks
- gocartStatue 7y agofrom their benchmarks: https://www.raspberrypi.org/magpi/wp-content/uploads/2019/06/2019-06-21-15_44_14-Window.png https://www.raspberrypi.org/magpi/wp-content/uploads/2019/06...
- HeadsUpHigh 7y agoI wouldn't be surprised if downclocking it would reduce the consumption even further. Also this was with a screen+kb/m attached so that's extra.
- peterburkimsher 7y agoYes, there are adaptors, but it won't fit with the same loopback HDMI board that's included with the screen. It'll need a wire, which effectively doubles the space it'll take up on a desk. If there are any other high-res small (<= 4") screens, please let me know - the highest DPI that I know is an iPhone 4S 960x640 3.5" screen with a Creotech adaptor.
- mustardo 7y agoCon for me is still SD storage :-( At least now an SSD over USB3 should be reasonably fast
- peterburkimsher 7y agoHow about a RAMDisk? https://hackaday.com/2019/04/08/give-your-raspberry-pi-sd-card-a-break-log-to-ram/ https://hackaday.com/2019/04/08/give-your-raspberry-pi-sd-ca...
- mustardo 7y agocertainly a good idea for stuff / locations that have regular writes, just be nice to use a more durable boot disk, hopefully booting via USB storage is well supported
- kingosticks 7y agoIt's well supported in the model 3 now so that seems extremely likely.
- kingosticks 7y agoI stand corrected. Turns out it's implemented quite differently and neither netboot or booting from mass storage is supported for pi 4 yet. Hopefully we won't have to wait long. https://www.raspberrypi.org/documentation/hardware/raspberrypi/booteeprom.md https://www.raspberrypi.org/documentation/hardware/raspberry...
