My experience between Android and iOS is limited to iPhone vs android phone and even if the iOS device was 3 times the price, I d still go for it I find the android interface to be like Windows 3.0 vs Vista... You sure can print from an iOS device, wirelessly... Being able to send music, pictures or video to a tv or stereo thru air play (with a $99 apple tv) is great...

I still have to get up and get that charter contract i printed wirelessly ... Darn. And the same pocket size device can be used as a backup plotter I the tender or to quickly look up distances and marinas
