Interesting marketshare graph. It shows 2 entries for Q2 2010, with the last one lumping in the iPad under Apple's mobile computing share. Apple goes from being #7 worldwide to #3 world wide, before the iPad was even out everywhere.

The thought behind including the iPad is that it is a capable mobile computing device for many and slots in at a price point below the main Apple notebooks, similar to a netbook slotting in below the normal Acer/HP/Dell laptops.

Even without the iPad, Apple's mobile division is doing well, showing growth even when the iPad came out. Seems it's not really cannibalizing Apple products, but may be eating competitors market share in the mobile space.
