I have received my shipment of Ubuntu disks from shipit.ubuntu.com
They are sending out single cdrom sets with stickers now, so get them while they are hot and start passing them out. If you see me at a User Group meeting, hit me up for one, I always carry one on me. :) The single disk can either be installed or run off the cdrom as a Live disk.
I have a MacBook and I run Ubuntu on it with Parallels. I put the Apple decal on my car and put the Ubuntu circle sticker inside of it. I’m just crazy like that.
I haven’t figured out what to do with my stickers yet, but the CDs are definitely very useful.
