I've done my sums and I think I've come up with the potential to buy all the necessary components, install the appropriate software (XBMC, on-demand, etc) and produce a nice media centre out of a Pi to sell on eBay and elsewhere, make a little profit and having fun along the way.
One of the most expensive components is the PSU. I can source a 5V 1A PSU for around £4 but I've read conflicting reports that a standard-issue LCD TV can power the Pi with its USB port. Has anyone had any experience with this? It would be a nice option to be able to attach the Pi to the rear of a flat-screen TV, connect it via HDMI and control it via a mobile device so it's nice and tidy. That's the plan anyway!
Thanks in advance,
