A blatant Chrome ad (with some misleading-at-best wording on the iPhone splash page), but it’s damn impressive and a lot of fun.
This is a Google side project at its best: a fun, technically impressive toy for geeks wrapped in a huge ad that’s mostly honest and probably well-intentioned, as long as you don’t think about it too much and you believe that it was created by a few geeks having a great time in a plush workspace full of laptops, free snacks, and colorful toys.
