For these to be the ultimate reviews and comparisons (e.g. trying to keep it positive!), they needs a few more sections:
1. Reliability. My mac hardware has already failed once, covered by AppleCare ($$), which only happened with my very first Toshiba, a long time ago.
2. Hidden costs. Are free security apps reliable? Is paid security reliable? Can you go without Apple care?
3. Out of the box security, MacOS vs Windows, any potential malware from a Chinese manufacturer in particular. In other words while a semi secure Windows is possible, how much effort and vigilance does it require from the user, in hours per day; it is up to the user how to determine the cost of this effort. What risks are average / most users running if they never install a decent security app: stolen bank and store credentials, lost info, blackmail, lost productivity.
4. Medium term durability. Not easy when you have to buy the laptops, but perhaps your readers can help.
