OmniWeb 6 is very usable in it's current state. I've always loved the way OmniWeb handles tabs. It would be great if OmniWeb could have a start page option like Safari's Top Sites or Opera's Speed Dial. I know there's a lot on OG's plate (can't wait for OF2 and OO4), but that would make it pretty easy for me to use OmniWeb more regularly.
