Total PC market, including tablets, grew to 124.5M units in Q3, up 23% YoY; Lenovo shipped 23.5M devices, up 11.6% YoY, Apple shipped 22.1M, up 41% YoY
Context & Ripple Effects
Canalys has spent the fall documenting a pandemic demand wave in pieces: an August report showed the Q2 tablet surge alongside a 26% desktop collapse, and October brought a 10-year shipment record for traditional PCs in Q3. This new cut of the data merges both categories into one 124.5M-unit market — and reveals what category-split views hid: Apple, powered by tablets, is now within 1.4M units of Lenovo's lead.
First-order effects
- Apple's 41% growth to 22.1M devices puts it effectively neck-and-neck with Lenovo's 23.5M, turning the PC market's #1 slot into a two-vendor race decided by tablet strength.
- Lenovo still leads but its 11.6% growth is roughly a quarter of Apple's pace, meaning its margin of safety shrinks every quarter the mix tilts toward tablets.
Second-order effects
- Vendors without meaningful tablet businesses are competing for a shrinking slice of the combined market — the same Q2 data showed desktops down 26% even as iPads grew nearly 20% — forcing HP and Dell to lean entirely on notebooks.
- Apple's trajectory gives it leverage to push further into volume segments Lenovo traditionally owns, pressuring pricing and channel positioning at the top of the rankings.
Third-order effects
- The pattern held: worldwide shipments went on to reach their highest annual total since 2012 in 2021, suggesting the combined PC-plus-tablet framing — not the old desktop-centric one — becomes how share leadership is measured going forward.
The trend: Pandemic-era computing demand is redrawing the PC vendor rankings around broad device portfolios, where tablet scale determines who can challenge for the top spot.
