I visited Zumbox yesterday, as it was mentioned in a post here. I was unhappy with the design. I felt there wasn't enough information there, and I grudgingly watched the video, only after I couldn't find information in non-video format. I should note that I am in the market for this service and only gave them the extra time I did, because of that. Were I a more idle visitor, that back button would have had skid marks on it. No, I didn't convert. I went with another company, also mentioned yesterday.<p>The author doesn't like "distracting nav links". Maybe. If I was an expert, I'd be rich. But after struggling with this stuff for awhile, it's my opinion that when the user's trigger finger starts getting itchy, he's going to click that mouse. On Zumbox, there's almost nowhere to click but away from Zumbox. Seems like it would be better to let him stay on your site at least.<p>Zumbox was notable for me, in that I actually had a negative opinion of it's landing page, where usually I'm neutral or I find things to admire about almost any established companies page.
