i have a new RPi Zero and paid a bit more than MSRP but i'm not complaining... combined with a $5 micro-hdmi plug, $12 HDMI->VGA adapter (Ableconn), donated Belkin wifi dongle-dingy from the sister-in-law, parts-bin 4-port USB hub, $5 USB sound card (Sabrent C-media), $1 wireless mouse and $2 wireless keyboard (from Big Lots), and a $9 thrift-store Dell LCD monitor, we have a nice little desktop for our guest bedroom down here on the Gulf of Mexico (the thrift stores 'round these parts are *great* for scrounging electronics - all kinds of stuff for $1 or so!):
total cost? US$49!!!
i'd say that's reasonable... but it is a shame that the Zero isn't in greater availability... think of all the possibilities...
