Yea, verily, Google brought Gears to Gmail today, meaning you can (finally) go through downloaded emails without a handy internet connection. There are caveats: spellcheck won't work, can't add attachments, pretty much anything that would require a connection won't be there. Reading, responding, starring and labeling do work, however, which is very cool. But hey, don't take my word for it. See the pretty movie Google made to explain it all below.


UPDATE: As pointed out in the comments, this is US and UK only (for now). Also, I should point out that you'll find the feature in Gmail labs -- it isn't yet part of the standard feature set. Google states users should see this by the end of the week.
