A report from market analysts IDC looking at market conditions in the United Kingdom says that in the first quarter of 2013, tablet shipments outpaced the combined desktop and notebook PC for the first time. A total of 2.8 million tablets were shipped in Q1, outpacing the 2.3 million PC units (which include Macs alongside Windows desktops and laptops) by a half-million units -- a rise of 188 percent year-over-year. While the report is limited to the UK, the results likely foreshadow future trends elsewhere.
