NPD: Apple Maintains Top "PC" Position on Strength of iPad

According to NPD, Apple remains the top "PC" manufacturer globally, largely because of the iPad. According to the NPD shipments (not sales) data, Apple had a 22.5% share of the PC market. Overall NPD said "PC" shipments (including tablets) grew 30% year over year.

However Dell reported earnings this week and missed analysts' estimates because of slumping PC sales. Dell was hurt by smartphone and iPad sales, which have taken the place of PC replacements for many consumers. 

Among tablet makers, NPD said that Apple had a 62.8% share. However these estimates -- based on shipments, not sales -- are undermined by various analytics firms that report well over 90% of tablet-generated traffic is coming from the iPad. 

Below are the NPD charts showing PC and tablet shipments.

While tablets increasingly can function as PCs it's a mistake to include them in the conventional PC counts. It's part of a different category of devices. By including tablets into PC forecasts and estimates it obscures the true state of the PC market.
