Ironically, Apple seems to be the one with the largest nominal number of
registered OpenType Layout features supported in the Mac OS X 10.4 (in
applications that use ATSUI one way or the other). However, since Mac OS
X only supports a small subset of lookup types, the actual number of
effectively supported features is smaller, but still impressive. Mac OS
X 10.4 is the first operating system to support your favorite
typographic feature, John: "petite caps" :)
