Do I need a Copilot+ PC to use Office in 2026?

Not at all. Office runs fully on ordinary hardware. Copilot+ is a separate Windows 11 hardware standard requiring a neural processor rated above 40 TOPS, at least 16GB of memory and a 256GB SSD, and what it unlocks is on-device Windows AI features rather than the Office applications themselves.

What actually limits how big a workbook can get?

The grid stops at 1,048,576 rows, but you meet a practical wall well before that. A workbook holding around 2GB of data in memory becomes unusable no matter how much RAM the machine has. Datasets past that point belong in Power Query or Power Pivot, whose compressed engine copes with many millions of rows.

Is a discrete graphics card worth it for Power BI or Excel charts?

Rarely. Integrated graphics on any current Intel or AMD processor render charts, dashboards and standard Power BI visuals without difficulty. A separate GPU only earns its place where the same machine also handles 3D, video or machine-learning work.

Can a 13-inch laptop work as my main Office machine?

For writing, email and presentations it is fine and the portability is real. For spreadsheets it is cramped: fewer visible rows, no numeric keypad and a narrower key layout. If it docks to an external monitor at your desk most days the compromise is easy; if that screen is all you get, go larger.

Which keyboard layout should I expect buying in South Africa?

Locally sold machines are overwhelmingly US International, which is what a South African Windows installation defaults to. A listing photo showing a tall inverted-L Enter key indicates a UK layout instead, where several punctuation keys sit in different places and the left Shift is shorter.

How much SSD space do I need if I use OneDrive?

Files On-Demand keeps most content in the cloud and pulls it down on access, so the drive holds only what you have opened plus the local cache. A 512GB SSD suits that pattern comfortably. Working offline regularly, or pinning large folders to the device, pushes the requirement up quickly.

Does a slower processor affect Word and PowerPoint the same way?

Not really. Word and PowerPoint are bounded by typing speed and page rendering, both of which entry processors manage. Excel is the outlier because recalculation is genuine computation, which is why a machine that feels fine for documents can crawl on a large model.

What battery life is realistic for a full day of Office work?

Eight to ten hours from a 50 to 70Wh cell on a low-power processor, provided the day is documents and browsing. Sustained video calls roughly halve it, because camera, encoder and radio all run continuously. A machine claiming fifteen hours was measured playing back a local video.

What Actually Makes Excel Feel Fast

Spreadsheet performance does not scale the way most buying guides imply. Excel can spread calculation across many threads, but only where a workbook contains formula chains independent of one another; a single long chain of dependencies is evaluated in sequence however many cores the processor has. A high single-thread clock therefore does more for a typical model than a large core count.

Memory is the second axis and the one people misjudge. Excel has run as a 64-bit application by default since 2020, so it can address whatever the machine holds, yet one workbook still degrades badly once it carries roughly 2GB of data in the grid. Power Query and Power Pivot sidestep that limit by loading into a separate compressed engine.
