Apple shipped over 13.5 mil­lion mobile PCs in Q2’11 for 136% Y/Y ship­ment growth, over­tak­ing HP for the top spot, accord­ing to pre­lim­i­nary results from the lat­est DisplaySearch Quarterly Mobile PC Shipment and Forecast Report. Nearly 80% of Apple’s mobile PC ship­ments were iPads, which reached over 10.7 mil­lion units, for 107% Y/Y growth. Apple’s total mobile PC ship­ments (note­book and tablet PCs) were 3.9 mil­lion units more than HP’s nearly 9.7 mil­lion units for the quarter.

Here’s the breakdown:

1. Apple, 13.6 mil­lion, 21.1%
2. HP, 9.7, 15.0%
3. Dell, 7.5, 11.6%
4. Acer, 7.0, 10.9%
5. Lenovo, 4.8, 7.5%

I am unsure that the iPad should be in the “mobile PC” cat­e­gory. The inter­nals of the iPod touch, iPhone, and the iPad are very sim­i­lar. All three use the same OS. Why aren’t the other two included in this definition?

DisplaySearch defines mobile PCs as note­books and tablet PCs, but what makes a tablet PC a tablet PC? The size of the dis­play? Would the 5-inch Samsung Galaxy Player 5 be clas­si­fied as a tablet PC?

When it becomes dif­fi­cult to slot in new devices into old cat­e­gories, it’s safe to say we’re in the mid­dle of a whole­sale tran­si­tion. It’s also safe to say Apple is kick­ing butt.
