I hadn't thought about it for a while, but given the recent Conficker outbreak, I got to rethink of the whole thing again. Now.... there was something that bothered me A LOT.... and it still does (though I'm not working with them anymore, I still feel like I'm a part of the family). They are still developing applications in-house using proprietary frameworks tied to Windows. And here is why it bothers me: They have invested and continue to invest time (hence money.. public money, should I add) on getting themselves tied to one proprietary platform.
