The biggest issue I have had with their subsystem is that of the file system (NTFS). The fact that I can't have long paths and can't soft link seem ridiculous.
NTFS has a functional equivalent to soft links in the form of reparse points, although I don't know to what degree that feature is exposed in the UI, if at all.
