For me personally
1- New Design is okay nothing revolutionary or attention grabbing.
2 - The old design definitely has a special place among regular posters and before just flipping the switch overnight, I feel a poll should have been in place whereas everyone would state their preference.
IMHO Regular Posters are the front in which brings about new posters, don't disturb their peace!
3 - Dinasaur forum admins which have decaying mentalities almost only associated with banning and deleting posts and in other times abusing their admin privileges, great job!
4 - Yes having a more responsive less cluttered mobile experience for xt is comparable to The downfall of Nokia and Blackberry, you either catchup or be left behind
