After tons of hiccups, from materials sourcing problems to having the wrong ethernet jack, the Raspberry Pi computer is now in stock in their warehouse. Shipping of the product will begin soon, and they said they will do it in the order that the products were ordered. That means if you were the #1 person to order one, yours will ship first. If you were #2, yours will be shipped after #1's. 

Glenn Jarrett, who is the Head of Electronics Marketing at RS Components (the company who received the shipment and will ship them out to customers), said:

"We are delighted to have the first batch of fully compliant products in our warehouse and to be able to invite the first wave of customers who registered for a Raspberry Pi to place their orders from this initial stock. There has been a great deal of anticipation for Raspberry Pi since its launch at the end of February, and it is important that we provide a delivery guarantee to customers when they place their order."

If you haven't ordered one yet but would like to, they will be accepting orders only when they can make sure they have stock for you. You can read the press release here.
