The ZX Spectrum Next

Has anyone had a look at the ZX Spectrum Next?

This machine is a reworking of the Z80 Spectrum that has a few modifications, such as:

7 MHz clock speed (the 28 MHz mode has been put on hold due to instability)
512 MB RAM upgradeable to 2GB
Wi-Fi options
Full Spectrum 128+ inspired awesome case
SD Card reader

We really are struggling to find a decent review of this machine by someone who actually has one. All of the YouTube stuff just seems to be people who only have the board rather than the whole machine, or are still awaiting their version...?

Can anyone shed any light on what they're like?

Currently there are a couple of ZX Spectrum plus systems for over £600 on eBay!

There is another Kickstarter open, so don't go eBay nuts - get it for the retail price!
