Ti seems to be more of an attempted trend that never really took off aside from a (miniscule number of cyclists who swear by it) than anything else.
Other than working on a ti few bikes here and there at the old shop where I worked, I don't really have much experience with it - but I can tell you that everyone I've ever encountered riding a ti road frame has been either a Fred or an extreme weirdo with more money than physical or mental ability.
Personally, I think the cost/logic ratio is way off and titanium is overkill for what most normal people use bicycles for. An All-City rep brought a Mr. Pink into the shop about a month ago and I highly doubt you'll be let down in any way by that bike.
