Now that I've had a few days at a PC to use this, I have formed an opinion.
I do like the name change ability, as long as it's used in moderation... I like the way it posts pics and gives you an instant preview. It does load much, much faster on the phone, but I do miss the Huddle app. Being able to vote up or down on individual posts is a nice feature.
The layout in and of itself isn't bad, there is a lot I like about it... but to me it is much harder to follow. Just visually the forums are harder to read... the quoted texts don't stand out as much and it takes a lot longer to go thru new posts than it did on vBulletin. The new content button is nice, but I also miss the way userCP showed your subscribed threads, which btw doesn't seem to work at all here...
Definitely some tweaking that needs done.
