Tablet computers are selling slower for the first time since Apple introduced the iPad four years ago, although to be fair, consumers still love them. Market intelligence firm IDC expects 245 million tablets to fly off the shelves in 2014. But, it was slow going into the first three months of the year. Shipments of new tablets fell 5% to just a little over 56 million units. Apple is the most popular tablet manufacturer in world with about a 20% market share, but Apple's shipments during the first quarter slid more than 16% to 16 million units. Some of the change can be attributed to users holding on to the devices longer, as many don't feel the need to replace what they already have and if they do upgrade, they give the older model to a family member or a friend, which makes them less likely to buy another one. Smartphone screens are also getting bigger and phablets are eating away at tablet's market share.
