it idles around 100ma, so there is never a need to turn it off.hmm not so impressed looking at videos online.
very slow boot time.
how will you hook up USB external hard drive? There are only 2 USB jacks and you need them for keyboard/mouse.
It has no enclosure so static electricity could fry it with all those components bare on the PCB.
you get a usb dongle, or you don't plug in anything but a harddrive. that's what I do, I don't use a mouse or keyboard- I use a cellphone.
I, as have countless others, have been using pi's without cases for a while now. no static death that I have had or heard of. its always grounded through the power input...
