No crashing on an iPad air for me (of which you DON'T need, Jake - you are using wifi). But mostly I use it for a little surfing and moderating on a web forum I belong to. No hard core reading.
(sent from my iMicrowave using tapioca talk).
I'm not sure I follow the WiFi part, iPad comes in WiFi only, that's what my wife has. In her case its the browser that crashes every few days.
