Why should I use Any method instead of Count?

[dinges]

I just wonder why should I use \[code\]Any()\[/code\] instead of \[code\]Count()\[/code\]?, if we took the msdn example :\[code\]class Pet{ public string Name { get; set; } public int Age { get; set; }}class Person{ public string LastName { get; set; } public Pet[] Pets { get; set; }}public static void AnyEx2(){ List<Person> people = new List<Person> { new Person { LastName = "Haas", Pets = new Pet[] { new Pet { Name="Barley", Age=10 }, new Pet { Name="Boots", Age=14 }, new Pet { Name="Whiskers", Age=6 }}}, new Person { LastName = "Fakhouri", Pets = new Pet[] { new Pet { Name = "Snowball", Age = 1}}}, new Person { LastName = "Antebi", Pets = new Pet[] { }}, new Person { LastName = "Philips", Pets = new Pet[] { new Pet { Name = "Sweetie", Age = 2}, new Pet { Name = "Rover", Age = 13}} } }; // Determine which people have a non-empty Pet array. IEnumerable<string> names = from person in people where person.Pets.AsQueryable().Any() select person.LastName; foreach (string name in names) Console.WriteLine(name); /* This code produces the following output: Haas Fakhouri Philips */}\[/code\]What if I used :\[code\] IEnumerable<string> names = from person in people where person.Pets.Count() > 0 select person.LastName;\[/code\]It will give same result ! , (I don't think it created for shortness or something) , is there any feature for \[code\]Any()\[/code\] ??
