ECC (including Curve25519) is not secure in a quantum computing world, Shor's algorithm solves discrete log efficiently.
I am not a deep expert in this field but there is a lot of work in post-quantum crypto that derives security from the hardness of some lattice-based problems instead of discrete log (E.g. New Hope being used in an experiment in Chrome is based on RLWE, I think).
Not an expert, but I think an important part of this is only releasing male mosquitoes, and separating them at scale is generally considered to be difficult (there have been other successful uses of SIT but always with different species).
From their FAQ it sounds like they have made progress on this front:
> What has Debug accomplished so far?
> We've developed methods for automated mosquito-rearing, and we know that we can separate males from females with high precision, and we’re continuing development of these technologies at larger scale in our lab.
Chrome 37 (the current dev channel) enables high-dpi support on Windows out-of-the-box (which might fix the issues you had with win8 mode -- at least, it seems to work for me).
The SP2 Wacom setup was not perfect by any stretch of the imagination, in my experience -- accuracy was terrible in the corners / near the edges, and parallax was a serious issue, if you did not write/draw with the pen perpendicular to the surface of the screen, there was a significant offset from the tip of the pen to where the line was actually drawn. These were bad enough to turn me (and at least one professional artist that I know) off from buying one.
The move to N-Trig hypothetically fixes both of these. Early reviews/videos say that corner accuracy is greatly improved, and the lack of a separate digitizer layer allows a thinner optical stack, reducing parallax (and allowing the device overall to be thinner).
Driver support has historically been an issue, but msft seems to be improving things significantly.
There are fewer levels of sensitivity and hovering doesn't work quite as well, but I am overall reasonably optimistic about the switch.
