Frequently asked questions
Which has the better display?
The iMac, by a wide margin on paper. Its 24-inch 4.5K Retina panel runs 4480 × 2520 at 218 ppi with 500 nits and P3 wide colour, so text and images are far sharper than the Dell's 23.8-inch 1920 × 1080 IPS panel (about 92 ppi, 250 nits). The Dell counters with a 100 Hz refresh, a 99% sRGB anti-glare finish and an optional touch panel — practical strengths, but not resolution.
Can I upgrade the memory or storage after purchase?
On the Dell, yes — and that is rare for an all-in-one. Its 16 GB sits as one module in two DDR5 SO-DIMM slots (to 64 GB), and the 512 GB SSD fills one of two M.2 slots (to 2 TB), so a second module or drive fits mid-life. The iMac's unified memory and SSD are fixed at order, so specify 24 GB or 32 GB up front if you need it.
Which is better for video calls?
The iMac. It carries the best camera Apple fits to a desktop — a 12MP Center Stage sensor that auto-frames you, plus Desk View, a six-speaker array and a three-mic setup, so a huddle space needs no add-ons. The Dell's pop-up FHD HDR camera, dual-array mics and 10 W stereo are solid for Teams calls, and its optional 5MP IR camera adds Windows Hello and presence detection the iMac's fixed camera lacks.
Is a keyboard and mouse included with each?
The iMac always ships a colour-matched Magic Keyboard and Magic Mouse in the box, with Touch ID on the keyboard as standard on 10-core models — nothing else to buy. Dell treats input as a drop-in-box option, but the stocked UK Pro 24 (XJP3R) is listed with a KM5221W wireless keyboard and mouse in UK QWERTY; tell us at quote stage if a fleet needs a different standard set.
