I've been kicking around similar ideas. I go back and forth on whether an all-in-one is better or not when portable/traveling (vs a separate PC/display.) There are pros and cons for sure to each.
Seems the zBitx has some bugs to work out on the FT8 front (per AE5X's blog), so by my view, it's not ready for FT8 POTA prime time yet. The DX-FT8 on the other hand just got a firmware release that allows SOTA/POTA and such, but I feel the <1w is a bit weak for reliable POTA/portable work.??
