nick.lidgett - I heard you can get them in maplins now\very soon. I'm not sure about a case but they have got Pi's + a kit with all the bits you'll likely need
Radiation - Saying that "artificial limitations are wrong" is rather silly. The people who invested time and money to make something "should let it be used for free"? Is your time free? If you work do you expect to be paid?
The chip manufacturer (broadcom) has sensibly built in support for technology that can be switched on and off (depending upon licencing). This means that if a particular technology in not required then it can be sold without that license more cheaply. This means that ONLY the people who need a technology have to pay for it. The is WAY fairer than everyone having to pay for stuff they won't use.
I would also congratulate the Pi Foundation for the selling price on these codecs. It would have been very easy for them to round these prices up to a fiver to help fill up the foundations bank account. They chose not to, and to sell for the lowest they could. If only others had the same attitude.
I get why they might do it but there's a right way to make money and a wrong way, clearly if the hardware is capable then it costs them nothing to allow it to run after it's already been included, the deal should be been between the chip maker and codec people and nothing to do with us.
You might not understand why such business practices are questionable but i assure you they are, i mean how far could it go? what if intel one day released a new chip that was capable of 10ghz but started out at only 1ghz and each addition 1ghz costs £100?
If the hardware is capable and costs them only so much to make then adding artificial limitations is pathetic.
