Agreed on Google Scholar. I actually prefer the interface of Microsoft Academic Search, but the coverage is just not good enough. Google Scholar indexes nearly everything, often within a day or two of it appearing on the internet. Whereas Microsoft has only managed to find about half my papers, and has somehow not managed to find any of them more recent than 2010. That's part of the difficulty in beating Google here, that before you can compete on user experience, you have to at least come close to matching their indexing.
