Getting a New Tablet

One of the gadgets that I want to get my hands on are tablets. I would like to buy a tablet for myself as recently they are gaining on popularity and I think that is because they can be useful in many situations. In the past I had a Pocket PC; however, tablets have a lot larger screen and due to this have higher productivity. Personally, I am planning to go with a 10 inch tablet as I want the screen to be pretty large. What I will need to ensure is that the tablet will be light enough to hold comfortably in my hands for long periods of time.
