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:
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.
