Um, if by "innovative concept" you mean "almost exact ripoff of uservoice", then yes, I totally agree.
It is a little cleaner and much closer to the rest of dropbox's site than they could get uservoice. I'll be interested to see if they regret reinventing the wheel and thus having to spend time solving problems uservoice has already solved.
There are obviously some benefits (same login as the main site, they can implement any feature they want, looks more like the rest of dropbox)
Well yeah, but they're still doing the same thing, which means that there are problems that uservoice has already solved that dropbox will have to deal with on its own.
For example, someone said that the search is really bad. Uservoice probably has invested a fair amount of time into searching liberally enough that it doesn't throw out tickets that do match what the user is asking for.
I don't know if it's been there before uservoice (I think so), but Dreamhost has this same thing on it's feature request area. You have a number of votes, can see all the requests, vote, and get them back once/when the feature you asked for is implemented.
