The number of hours of work-from-home that Google gets out of those laptops more than justifies their cost. Hell, I'm posting this from my work laptop, taking a break from writing out a whole bunch of use cases and product design decisions.
Very broadly, Search Features. I worked on the visual redesign that launched last May, and before that some of the search tools (particularly Wonder Wheel and Related Searches) and a bit on the move from having separate search properties (books.google.com, blogs.google.com, video.google.com, etc.) to a single search app. Then I spent about 6 months doing some infrastructure stuff with the webserver, and I'm now doing some feature work that's in the early stages of the project.
Cool. What tools do you use for daily design? I've been slowly moving from Photoshop to CSS, and want to start using stuff like Antetype early in the process. I've also figured out that Photoshop is good for finalizing a design that's been moved around, tested and iterated upon.
