I use a Mac and much prefer it, but it does have disadvantages.

One is the lack of standard keyboard shortcuts for menu items across apps - on a PC, you can always hold down Alt-F and drop down the File menu, Alt-E for the Edit menu, and so on, and then go on from there to use the functions within that menu.

Another is that websites - mainly civil service websites or company websites for things like getting paid for work - often won't work well with Macs, and the people in charge of those functions are usually ordinary people using bought-in programs, and so can't change the programs, even if they should be expected to, which is another question.

And printer drivers for Macs are almost universally crap. Unless you buy Apple printers (too expensive), you're stuck with somethng like a HP. On a PC, it will have options like "Print selection"; on a Mac, you can usually only print the whole document or specific pages by number - which, on websites, is a matter of guesswork.

Also, printers often won't work with specific programs. I can't print from Adobe Acrobat, for instance; to print a PDF I have to open it in Preview and hope for the best - again, with the very limited driver not helping.
