Instead of having the usb port only support usb play back allow it to have a gig nic with a usb hub for faster speed when streaming and navigating the interface. It is night and day difference on the Express 4K+ with OTG cable and a usb hub with gig nic. The wireless speed on the ultra is ok not great. The Streaming stick 4k gets better speed on wireless than the Ultra. The streaming stick 4k also supports a otg cable and usb hub with nic but you have to use your phone for a remote. I think for all the Roku streaming devices should allow this feature. And have a remote that is not wifi only but bluetooth.
