So you have to manhandle the board to switch it on and some cases don't cover gpio pins, how careful must you be about short circuiting the board. Also what are you suppose to grab onto when turning on, and can you kill the board by mishandling it?

I'll use history search extension then, although I suspect that indexes stuff on the device and not servers.

I've read that raspbian chromium is optimized, how significantly so?

I want my history sync between browsers, extensions on mobile, which precludes me from using chromium, unless I can sync that chromium with Yandex browser on mobile.
