Looks quite interesting, apparently between 2x and 3x the performance of the raspberry Pi4 for pretty much the same price (within a couple of pounds). Notably there are quite a few upgrades and new features like the addition of a PCI Express 2.0 controller and an accompanying M.2 hat. Significant because you should be able to attach an M.2 NVME storage device directly via M.2 at 500MB/sec.
(which is about twice the current effective maximum via USB3)
This looks like the first version that would make a proper desktop machine, and an even better home server than the Pi4.
Incidentally, the killer feature for me of the Raspberry Pi; they’re made in a factory just down the road! So supply chain issues aside, they’re one of the few (only?) Linux compatible computers actually are manufactured in the UK!
