I have a Samsung Galaxy tab and an iPad and I like them both...for personal use that is. I find outdoors, the screens are difficult to see, defeating the purpose of having nicely prepared maps. Also, I'm hesitant to use them in poor weather; battery life is terrible when using wwan and gps in colder temps. 2nd'ly, they are not protected against humidity or rain/snow. You can get otterboxes and protective cases but these are not perfect and do nothing in cold temps. I found what I believe to be a great product, the Xplore RangerX. It's a highly ruggedized Android 4 tab and unlike many rugged tabs, is inexpensive. The screen is fantastic outdoors and battery life and does well in wet/colder environments.
