Have no experience of the small iPad but I did try the iPad. I didn;t get on with it, and it went back, very much a personal thing, but to me it didn't live up to the hype.
I have just upgraded to the Note 2 from the Note 1, which itself was an upgrade from the S1.
No complaints except the usual Samsung ones - too much drossware and slow implementation of o/s upgrades.
Impressed with the battery lfe on the Note 2.
Get as much "hands on" with both as you possibly can.
