Re: Cost
Or to put it another way. £26 for a pi, get an 4gb uSD card (2gb might be enough, cant remember) from back of the sofa or ebay for £2, a cheap psu that can supply 5v for £2 on ebay, download openelec and you have a fully functional media centre that can have internet radio, youtube, iplayer, streaming.... all for £30
Seriously I spend more than that at our local takeaway per month.
It is small enough that you can glue it to the inside of your TV if you so require. Have your TV power it from a usb/relay/voodoo séance and it is wife friendly. Openelec works with cheapy windows remotes+usb IR so what more do you want?
