Nielsen’s survey didn’t go into how exactly consumers were using their tablets, but I assume they cover the mundane email checking and casual web surfing for many users. A Google AdMob report from last month said that consumers mostly used tablets to play games.
According to Nielsen’s data, tablets also negatively affected netbook usage by 23 percent, and ereader usage by 24 percent. Tablets also caused 26 percent of portable gaming console owners to use those devices more, as well as the same for 25 percent of Internet connected TV owners and 22 percent of netbook owners.
The top reasons for using a tablet instead of a computer included the fact that they’re easy to carry (31 percent of users), they offer easy to use interfaces (21 percent), and they feature fast start up and shutdown (15 percent of users)
