Agreed, Soon it will get too tiresome to keep playing with the date, I would rather just pay.
Then again almost any copy protection can be beat, so go with what works and spend more time making a great game than worrying about the ultimate protection.
As I final thought they can always keep downloading the trial to play. I suggest simply a demo with only 1 level or a crippled version with out a key feature or save.
