Thanks for the compact comparison!
(Small typo on the ROM sizes, it's GB, not MB )
Are you sure about the 4GB RAM? I would expect them to finally ditch the 4GB RAM on the base variant at this point... I can't believe HP and every other major manufacturer still offer their base model with 4Gb of RAM on $1000+ high end computers when 8GB RAM is below $50 for a manufacturer. So basically, if you want this tablet with 8GB RAM, you will have to resort to next tier and spend at least $1300+ (I guess?) or "service" it at day 1 (invalidating your guarantee, I'm guessing?).
That (and price, of course) would be quite a showstopper when comparing the entry level offerings (HP Elite x2 1012 G2 - i3 vs Eve-V m3)...
EDIT: PcWorld confirms this:
(link) The base $1,099 Elite x2 in the United States will have the Core i3 CPU, 4GB of LPDDR3-1866 SDRAM, and 128GB M.2 SATA SSD.
Not impressed at all by the RAM.
