Looks pretty comparable to the S7 and certainly an appreciable upgrade to their last two flagships.
Compared to the S7, it's lacking waterproofing and wireless charging. It's also non AMOL.
On the positive, it's got a slightly larger screen and type C USB.
And you've got to wonder, HTC's also in a pretty perilous financial position, so will they still be around in 12 months time to provide updates?
OK, a couple more positives for the 10 over the S7, better speakers and support for hi res audio.
Biggest plus is easy to unlock the bootloader, root and your warranty is still in tact
