We have 2 OLPCs floating around Europe now, both of which are likely to end up at LinuxTag.
I think that the people who are demonstrating them need to make sure they can appropriately talk about what has happened lately with the whole OLPC/Windows saga:
We should focus on the Sugar interface, and making sure people know that this interface is still being developed, regardless of whatever else is happening with OLPC itself.
