I also am not a fan of the slanted nav. As a user and as a developer (knowing the CSS/image requirements involved in pulling that off), I strongly prefer the normal boxes. I don't mind either color scheme. The attendhub logo is ok except for the small 'a'. It seems forced just to make room for the playful interaction with the figure grabbing the 't'. I don't think the figure and its action are very clear in terms of what that means to your brand. Perhaps incorporating something clock-like (although very simplistic) with the style of the MinutePortal logo would work. Finally, not a huge fan of the "curvy-edged" shadow on the MinuteHub nav bar, but it's not horrible.
