The latest tablet shipment forecast from IDC projects that Android will take a 48.8% share of the tablet market in 2013, a significant jump from the 41.5% share of the market the platform held in IDC’s previous projection. The rise of Android in the tablet realm comes at the expense of Apple (AAPL), which IDC projects will hold a 46% share of the tablet market in 2013, a decline of five percentage points from the 51% market share it held in 2012.

Only one problem, actually two.

These forecasts are made without any input of sales of new iPad versions and secondly there is a chronic shortage of android tablet apps.
