What the other guys said and I'll add one more thing. Your temperament should be the deciding factor; if your willing to put up with some bugs for the overall experience then go forth young man, you'll love this sim. If you are likely to get frustrated by things like spending 5-10 minutes setting up the belting on your guns then loosing all of it the second you leave the screen, then you might want to wait a bit.
As for my Dispassionate Opinion on CloD: It is by far the best flight sim ever made, it was simply released to soon. Don't worry about all of the naysayers, it won't take anywhere near as long as some of them think to get this thing up to snuff with all of us Beta testers out there helping out.
