It is the most common kit question we get, and the honest answer is not 'whichever is cheaper'. A desktop and a laptop solve different problems, and buying the wrong one quietly costs you for years - in productivity, in support tickets, in early replacements. Here is how to decide per role, in plain business terms, without falling for the spec sheet.
Start with the person, not the price
The right machine is decided by how someone works, not by which is on offer this month. Before comparing anything, answer one question for each role: does this person need to work in more than one place?
A salesperson, a director who lives in meetings, a carer or surveyor out on site, anyone who hot-desks - they need to carry their work with them, and that points firmly at a laptop. A till operator, a CAD designer, a finance clerk who sits at the same desk every day - they do not, and a desktop will usually serve them better and cheaper.
What a desktop genuinely does better
For a fixed worker, a desktop wins on the things that actually matter day to day, not just on headline price.
- •More performance per pound - desktop parts run cooler and faster than the squeezed-down versions inside a thin laptop.
- •Longer life and cheaper repairs - a failed part is usually a swap, not a write-off, and you can add memory or storage later.
- •Better ergonomics by default - a proper monitor, keyboard and mouse at the right height, which a laptop only matches once you add a screen and dock anyway.
- •Harder to walk out of the building - a meaningful security and data-loss point for many firms.
What a laptop genuinely does better
A laptop is not just a portable desktop; flexibility is the whole point, and for the right person it is transformative.
It enables hybrid and home working without shipping a tower around, keeps a director productive in the back of a taxi, and means business carries on if the office is shut. The trade is real, though: for the same money you get less performance, repairs more often mean replacement, and a small, valuable thing that leaves the building is easier to lose or have stolen. That last point is exactly why laptops make device encryption and the security basics we cover under endpoint security non-negotiable.
The hidden cost both sides forget
Sticker price is the least interesting number. A desktop needs a monitor, keyboard and mouse, which a laptop has built in - so the gap narrows the moment you kit out the desk. A laptop, conversely, almost always needs a docking station and a screen to be usable for a full day, which adds back much of the saving.
The bigger figure is total cost over its life: support time, downtime when it fails, and how soon you replace it. Laptops typically live three to four years and desktops four to five-plus, and a desktop's repairability stretches that further. We set out how to think about whole-life spend in how much a business PC should cost and when to let one go in when to replace business computers.
The pragmatic answer most firms land on
In practice, very few businesses are all-desktop or all-laptop. The sensible pattern is to match the machine to the role and standardise on a small number of models so support stays simple.
A common, sane split: laptops with docks for anyone mobile or hybrid; desktops or all-in-ones for fixed desks, tills and reception; and a workstation only for the handful of people doing genuinely heavy work like CAD or video. If you want to weigh specific models side by side rather than categories, our comparison tool lines them up on the things that matter, and the laptops range covers the mobile end. Decide by role first; the hardware choice then makes itself.
