Hey, now there's a good use for those stickers...ha!
I had my Powerbook with me on the first day, and the IT department was very amused and had fun setting it up. Had trouble with Airport/wifi connection, but with an Ethernet cable it was networked beautifully.
I'm in marketing, and I subscribe to a lot of marketing-related RSS feeds and podcasts - was happily setting everything up and getting productive with iCal and whatnot, until I got shut down. It only took a few hours before someone came by and said that's not allowed. 🙁
