It's not often that the folks in Redmond get to debut a new operating system as big as Windows 8, so we can't really blame them for going on at length about every feature of it. The latest to get the in-depth treatment on the Building Windows 8 blog is the Mail app, which has already gone through some fairly big changes since the Consumer Preview and is apparently set to receive even more before the final release. As Microsoft's Jeremy Epling explains in the post, central to the latest version is a three-pane view that's designed to take advantage of the 16:9 ratio Windows 8 is optimized for, and make the best use of all the space afforded by the full-screen "window" -- the latest release is now able to display 14 messages at a time at the standard 1366 x 768 resolution, for instance, as opposed to just 8.5 in the Consumer Preview version. It's also, of course, deeply integrated into Windows 8 itself, even taking advantage of a new networking APIs to detect if you're on a metered network and only download the first first 20KB of each message body if that's the case. Unfortunately, Epling didn't divulge much about those promised future changes, noting only that there are "many more features on the way." In the meantime, you can find out more than you may have wanted to know about Mail in its current state at the link below.
