In my opinion the sandbox is still out there, especially for sites competing for competitive keywords.
I think a new website can do better than a 10 year old site, but not over night and not just from backlinks. Strong overall SEO can do great things.
From experience, I believe aged domains definitely has advantage over new domains but maybe not quite as significant as it once did. Although their has been recent debate over aged links, I do feel links add value as they age.
