Those diminutive $25 Raspberry Pi computers are finally set to launch later this month -- if you absolutely can't wait to get your grubby paws on one, however, good news: you can pick one up early at auction, if you're willing to pay a little extra. The foundation behind the ultra-budget educational computers is giving buyers a head start, listing beta boards up on eBay. At present, the top spot belongs to beta board number 10, which is currently cruising at around £2,100.00, with about two days left at auction. If you're lucky, however, the low-end number five, which is currently priced at around £620, shouldn't increase too much in the next four days or so. And look on the bright side, all the money is going to charity here, so you can't feel too bad about yourself. Right?
