I almost forgot, but I heard about the following link yesterday. Regardless of one's opinion of Microsoft or their products, this has to be one of the most awful videos ever inflicted on anyone. (For background: MS are trying to persuade their customers to advertise the new operating system Windows 7 on their behalf.)
You can choose whichever activities are best for you. Because it's your party Ye gods. Ever get the feeling that whoever thought of this campaign has never been to an actual party?
(For what it's worth, I've no idea how Windows 7 will be radically different to Vista. All I've read about it makes it sound like Vista with more flashy things that nobody really needs. I tolerate Windows, and have Vista on my home system. I actually like one thing about it a lot, namely that you can search for any file and find it in less than two seconds. This was impossible in previous Windowses. Though, presumably, v easy with a Mac.)
UPDATE: After you've watched that one (or stabbed yourself in the face to make it stop, whichever comes first),
watch this one. Aha, I say, ahahahaha. Internet, we love thee.
