I can only speak for myself, of course, but there are at least two
major problems with it:
1) It is proprietary, albeit reverse-engineerable, making it difficult
to access your data without Mac OS X.
2) It doesn't correctly escape strings, producing all sorts of fun
results if you encode the string "$null":
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:
@"$null", @"key", nil];
NSData *data = [NSKeyedArchiver archivedDataWithRootObject: dict];
NSDictionary *dict2 = [NSKeyedUnarchiver unarchiveObjectWithData: data];
