Currently, my S7 would get between 2-4 hours constant use. I believe the battery is around 2200mah, so I think when compared to a Galaxy Tab, that's kind of sensible (6-8 hrs, 4000mah?). Given the extra weight, ~1.25 lbs, battery life is not so good. However, it has AT&T 3g freqs, and only cost $250 on sale. The Slim goes for around $299, so I'd expect the mediapad to be a bit more. I agree with you Capt'n, if we're only talking around $100 more for a quality device, I'd pay it. I only got the S7 because I wasn't sure if I'd use a tablet much, and for $250, it had decent hardware, a local return policy (best buy), and I thought a better bet than some of the $150 tablets out there. If we're talking $399 for the mediapad versus the Transformer, it'd be a tossup, but I'm leaning towards the transformer (depending on specs) as a better known quantity with probably better support.
