tested this in Taipei last month, it's size is actually quite similar to the 10.1

if the price is similar to the 10.1 as well, i'd advice u to get the 10.1 just because it's a full size tablet, watching movies will be much nicer, it's not really that big when u hold it, and it's super light weight.

If u want a smaller tablet to carry easily, get the 7.7, the super AMOLED display will make everything look nicer.

If u can wait, don't buy any samsung tablets, wait for the Transformers 2. that will be fantastic!
