Shipit is useful for people who can’t download Ubuntu’s large ISOs to burn or just want lots of CDs to give out. So many were disappointed that Shipit did not ship Ubuntu 6.10 CDs when it was released. Shipit has been shipping Ubuntu 6.06, which is a long term support release.
The good news is that Shipit will have Ubuntu 7.04 CDs! I expect they will be getting a lot of orders.
