The fact that 55% (or whatever) of the market is using the tool, but you aren't part of that 55% makes the claim accurate and the tool not right for you at the same time.

But if you want to plan a conference booth with a graphic designer, a professional marcom event planning, and some company principals, I can vouch for the fact that Basecamp is awesome.
