I know I mentioned these earlier, but I think that these are flaws that should be addressed:
The quick-search lacks a button, thus requiring a press of the enter key. If this doesn't seem like a problem, then keep in mind that many devices (tablets, smartphones, consoles, etc.) lack a keyboard. While some of these devices automatically submit search queries once they're entered, many don't, rendering button-less search forms unusable. For this reason, the quick-search ought to have a button.
Text in text boxes is simply too dark. It looks like it's grayed out. Also, people with vision problems or crappy displays might not be able to read it. A text color of #999999 or brighter would be sufficient.
In case you don't know what I am talking about, I have attached some screenshots to illustrate these problems.
