I'll chime in. The 'evolution' of Romanian language treatment in Windows OS is discussed at length here:
http://secarica.ro/.
Personally I would have nothing to do with a keyboard using Romanian diacritics in place of [,] etc.(especially since they use cedilla, but also because ...) Nowadays, a very popular Romanian layout, available in Windows *and* Linux, is the so called 'programmers layout', in which ă, î, ț, ș, â are composed using a, i, t, s, q + AltGr, while everything else is US compatible. Since I don't have to switch between US and RO layouts anymore, I find this layout to be a perfect one. Unfortunately, I think a lot of water will pass from Danube to the Black Sea until I will see a keyset showing these diacritics, correctly, near the above letters.
