A few late thoughts from me:
Anyone spending a lot of time at a keyboard should ONLY be using a desktop. Health and safety rules prohibit employers from providing their staff with laptops at their workstations, rather than using desktops, as the poor posture which results from regular use of laptops can lead to back and neck problems, as well as hand, arm and wrist stress injuries. What is law in the workplace is also common sense at home.
For the same amount of computing power, desktops are generally significantly cheaper than laptops.
Replacing peripherals on desktop installations (such as keyboards and mice) costs very little. Spill your coffee over a laptop keyboard and its touchpad though and you're facing a big bill.
For optimal image quality, a standalone monitor will always be far better than a laptop screen. (With most laptops you can only adjust the brightness. With a proper monitor you can optimise the brightness, contrast, gamma and colour balance).
A mouse gives greater ease of control over a cursor than a touchpad can.
'Not responding' problems on a computer are usually related to something which is hogging all of its resources (so that the web browser, or other software, can't do its job properly). In well over 90% of cases the problem turns out to be that the 'update' element of the relevant antivirus software has got stuck in a loop. (Microsoft's own antivirus software solutions, such as Microsoft Defender, are notorious for it but other products occasionally exhibit the same symptoms). The solution is to uninstall your antivirus program and then reinstall it (or, possibly better, to install something else).
