After a handful of delays, the $25 Raspberry Pi system is expected to ship very shortly. Some customers are already receiving e-mail alerts telling them that shipment of the devices is imminent. This means that lucky customers will get the Model B version of Raspberry Pi, but there are others complaining that they're having issues using their e-mailed voucher codes.

The problem is the amount of customers demands of the unit, rushing to complete their order has crashed the website. E-mailed voucher codes are being distributed in the order in which they were received, which is said to stagger customer arrival on the order RS Components site. What some people are doing, is jumping on the site without their e-mailed voucher code, which is causing more problems.

The device should hit users door steps over the next week or so, with the Model B ($35 version) sold out of its pre-order stock, with the cheaper $25 Model A version not yet in production. The cheaper version drops two USB ports as well as its Ethernet connectivity.
