display

You can do a lot of great things with field display in Drupal 7's 'manage display' tab for a content type. You can control the order and label position of each field attached to a node type in that tab for Full node displays, Teasers, and RSS displays (or other displays you set up).

However, there's no way to change certain aspects of a node's display inside an RSS Feed, such as the 'creator' tag, the 'link' tag, or the 'title' tag. For a news aggregation site I run, I wanted to modify the <link> tag when displaying 'story' nodes, and make the link tag give an absolute URL to the original source instead of to my drupal site (so, instead of http://www.mysite.com/node/12, it would go to http://www.example.com/original-story-url).

A lot of blogs also use this kind of format for reposted blog items (such as Daring Fireball), so users go straight to the source when they click on the title of an item in their RSS reader of choice. My method below can be modified to conditionally change a link if a field has a value (say, a 'RSS absolute URL' field or something like that).

[Update: It looks like Mountain Lion finally restored this functionality—you can press Shift + Control + Power key, and the screen will immediately go to sleep.]

The 2010/2011 MacBook Air models are all amazing, and I believe Apple will eventually convert all their Mac laptops to the same basic design (just different sizes), forgoing the optical drives.

The only downside to this new design is the lack of an eject key—of course, most people probably only knew the key could eject discs, so it's no big loss for them. I, however, use that key in a standard Shift + Control + Eject combination to instantly turn off my Mac's display to conserve power and prevent any pixel ghosting. I've used the combo for a few years, and it took me some time to find out a way to reliably do something similar on my new 11" MacBook Air.

There are a few ways you can get this functionality back:
