Still unconvinced we’re headed towards a post-PC future? We can at least conclusively say we’ve entered a post-netbook present, as Q2 2011 marks the first time their numbers have been eclipsed by tablets, according to ABI Research. 13.6 million slates were shipped in the quarter, besting the 7.3 million the diminutive laptops were able to clock in. When compared to the prior quarter, that works out to 112 percent or 7.2 million increase (!) for the former, and a 1.1 million decline for the latter. Cost apparently isn’t a driving factor, as the firm notes that tablets pack an average price of $600 — nearly double that of their trackpad-toting brethren. Oh, and in case you were wondering, 68 percent of tablets shipped were of Cupertino’s flavor. More cold hard facts await you in the PR after the break.
