Adobe Edge Inspect vs Ghostlab
When working on responsive sites, I generally have my 3rd-gen iPad, my iPhone 4S and a Nook Color running Android in front of me. And for good measure, another Macbook running Windows 7 with Internet Explorer. The real pain is loading up the same page on every device, then having to go back and refresh them all every time you make a change, which is usually every minute or two.
