So an Ipad & Ipod do the same thing?
No an ipod is for playing music only,ipad is much bigger and does everything,but it is basically a 'Tablet' but the most well known one as it was the first.
Not necessary the best one though just the most well known.
Here are some reviews but it's easy to find just Google 'tablet reviews'
