We (at bugsense) have about 500k requests per day and some of the are very intensive. Currently we pay $5.40 daily and it will go up to $22. So per month with the old pricing we ll be at $162, with the new pricing we ll up to $660. It's x4 increase and that makes it bit cheaper than EC2 for the same amount of data. If we subtract the administration cost it makes it cheaper. The old, cheap days are gone :( But still it compares well in comparison to other popular cloud solutions.
