This was the first boot of my new Raspberry Pi. I'd plugged it into the TV as a monitor along with a spare tiny keyboard and mouse. The lack of a MicroSD card was nearly a spanner in the works, but then I discovered one languishing in my old HTC Desire S. This was nearly scuppered by the lack of SD converter until I realised I could (with some trickery) connect the HTC to my Mac in order to format and copy over the NOOBS image successfully. Then install took 20 minutes or so by which time I was fairly tired and ready fo bed. Once booted I wiggled the mouse in Debian to prove success then shut down.
