I've had good luck with an old unused iPad2 (second generation, 30 pin connector) using a refurbished iPort Launch wall mount I found on ebay. The iPad runs ActionTiles and has uptimes measured in months before the safari browser process crashes and needs to be relaunched. The iPort ipad case and base unit set me back less than $50, I'll consider the iPad free because it's so old and slow it has no residual value.
