We dont really need a Pi killer anymore. They've done a fine job of killing it themselves. Their community has shrunk massively due to low cost mini pc's being leaps and bounds better value than a Pi now. Their two fingers being put up at the hacker/tinkerer hobbyist market over the last few years combined with the IPO and shift to B2B has made it very clear where their priorities lie.

Unless you need the GPIO theres zero reason to overpay for a Pi 5 for example when you can pick up decent second hand mini pc's on ebay for a lower price.

Case in point, a couple of months ago I was able to nab two brand new still in box Dell Optiplex 3050's (Core i7 6700T 4 Cores, 2.8Ghz, 16GB RAM Win 10 hardware license, 256gb ssd, with mouse & keyboard) for £55 each delivered. The base 4gb model Pi 5 comes in at £80-£100 once you add power, storage and a case.

Sure, its not ARM but you're not likely to be doing anything that _needs_ ARM.
