Each OS has its own quirks. I bought a Mac in 2011 my first ever after about 18 years of Windows PCs which included about 17 years of Linux. I still use both, I even have Windows 8 and Ubuntu 12.10 with Unity. Macs can be infuriating with some quirks such as no true delete key only backspace which for ex-PC users is labeled "delete". (Yes I know fn+delete=PC style delete). On a Mac you click a file to highlight it then press delete key gets? Nothing. The intuitive reaction would be it deletes the highlighted file, nope. Sure command+delete but a mouse click and then two keys really? Very inefficient. Transferring files to a USB stick such as an mkv refuses to move. Lots of space HFS, FAT32 or NTFS formatted? Nope, won't move.
