If you're like me, you'll be watching the inauguration from your desk. (The joys of the modern workday.) Thankfully, the events will also be covered online. Check out all the options available to people who are stuck at their desks.
It's also available on Hulu. (And then afterwards, you can watch your favorite episode of Buffy and think about how she could be Secretary of Defense.)
Also, check out the schedule of events. Obama's getting sworn in at noon, but there's a ton of stuff before and after to distract you from your usual work.
