Yes! I've pretty much watched it to death... I was always an Acorn fan, but these days I also have a ZX Spectrum Next.
Ooh. The Next is a premium item, isn't it?
It was such a great idea that I couldn't not jump on the Kickstarter. It was a little pricey, but the case, build, presentation and software were all terrific. The team did an amazing job.
It looks beautiful from the pictures I've seen. I'd love to own one, but cannot justify the price. I didn't have a Speccy but a C64 as a kid, so I went with the cheaper (and more cheaply built) TheC64 from RetroGames Ltd. It's just a working keyboard C64 lookalike with an ARM inside running an old version of VICE.
The Next looks like a much more premium thing. I'd really like one ;)
If you want to properly go down the rabbit hole as a C64 fan, then there's always the Mega65 (https://mega65.org/). Makes the Next look like a bargain-bin item.
