of course for modern Microsoft addicts the Surface is pretty good, I think the pro models are the ones that really hit the spot.

One of my bugbears with the android tablets is that a lot of the models get stuffed with bloatware which I don't need. Lenovo seem quite bad for this. If android is the answer then as you are already used to Samsung I'd suggest sticking with the brand to minimise the learning curve and we know it is quality gear
