iPad leads the tablet charge as mini-notebook shipments plummet
In the second quarter of 2010, shipments of mini-note/tablet computers were down 4% quarter-to-quarter (Q/Q), but up 29% year-over-year (Y/Y). However, without the 3.3 million iPads shipped in the quarter, shipments of mini-note/tablet PCs would have been down 14% Q/Q and 13% Y/Y.
