OK, the Advanced division wasn't so advanced and some of the Sudden Death problems were simply one-liners but the fact that MS even includes Perl like this is commendable. Trivial as it may seem, events like these are good PR. Personally I had fun and was a little sad that more people didn't participate (I was the ONLY entrant from my country).
For feedback to MS at the end of the event, I wrote a glowing praise for their "enlightenment" of including Perl but stopped short of promising to buy copies of Vista for friends and relatives.
