Have recently googled the same question and looked at what the "experts" say. From the googling, I deduced that they were 6 of 1 and half a dozen of the other.
SWMBO has an ipod touch 32 and loves it, I have a Samsung phone and think it is great. So in terms of home use, either the ipad2 or the 10.1 would do. I have marginally more adaptability than SWMBO, so we'll go for the Apple - although I detest their highly unlawful RPM.
They are all a complete rip off as "real" light weight lap top type computers give you more functionality for half the price.
