What's the concrete advantage of defaulting to Vista? Performance?
Yes, mostly. Vista has builtin support for condition variables and read/write mutexes, for example. Compiler-based TLS can be used safely with dlls. GetTickCount64 can also be useful in some contexts and is difficult to emulate. All these features will find their use at least in Boost.Sync and Boost.Log (the latter currently uses its own protocol for enabling use of these APIs, but it will be ported eventually).
Some of the things I really look forward to when I personally can drop XP support is the Slim Reader/Writer (SRW) Locks [1], the ability to specify relative RPATHs in manifests, SHGetKnownFolderPath (actually handles paths longer than MAX_PATH) [3]. There are a lot of neat stuff all over the API which is gated by being introduced post-XP. [1] http://msdn.microsoft.com/en-us/library/windows/desktop/aa904937(v=vs.85).as...
