Apple CEO Tim Cook stated earlier this week that the iPad experienced its best June quarter in almost a decade during Apple's earnings call. IDC has released its latest worldwide shipment figures, which underline Apple's dominance over all other tablet competitors. Apple will update the iPad Mini next, after refreshing the iPad Air in 2020.IDC estimates that Apple sold 12.9 million iPads during the second quarter. Samsung is the closest competitor, with 8 million shipments. Samsung's Galaxy Tab S7 tablets are a great choice for tablet users. They have a lot to offer, including a powerful hardware design and OLED screens. However, they are still limited by Android's poor selection of tablet apps. With 4.7M units shipped, Lenovo and Chrome OS tablets continue to be well received. Amazon was fourth with 4.3 Million Fire tablet shipments.As people adapt to remote learning and working at home, both tablet and PC shipments have increased dramatically over the COVID-19 period. IDC's statistics show that Chromebook shipments increased by 68.6% year-over-year and reached 12.3 Million units shipped in the second quarter. Although this was not a record quarter, it wasn't far behind the previous two quarters which saw new highs, IDC stated.IDC points out that there could be a slowdown in Chromebooks and tablets sales due to continuing chip shortages and an increase in consumer demand as more people return from the classroom or work. Apple stated that supply shortages could affect iPad sales over the next months. The iPhone may also be affected.
