Is there a difference between using two "where" clauses or using "&&" in my LINQ query?

When writing a LINQ query with multiple "and" conditions, I can write a single where clause containing && or I can write multiple where clauses, one for each condition:

static void Main()
{
    var ints = new List<int>(Enumerable.Range(-10, 20));

    var positiveEvensA = from i in ints
                         where (i > 0) && ((i % 2) == 0)
                         select i;

    var positiveEvensB = from i in ints
                         where i > 0 where (i % 2) == 0
                         select i;

    System.Diagnostics.Debug.Assert(positiveEvensA.Count() == 
                                         positiveEvensB.Count());
}

Is there any difference other than personal preference or coding style (long lines, readability, etc.) between positiveEvensA and positiveEvensB?

One possible difference that comes to mind is that different LINQ providers may be able to better cope with multiple wheres rather than a more complex expression; is this true?
