I always maintained with Windows 7 that Microsoft should cut through all the crap and . My feelings haven't changed with the Windows 8 versions.

Your grandmother, or your cousin may not need some Windows 8 Pro features like the ability to join a network domain or use Group Policy. However, Microsoft has a habit of leaving crucial capabilities out of the consumer version--especially security features.

With Windows 8 Pro, you get BitLocker and BitLocker-to-Go encryption, and Encrypted File System (EFS) to be able to encrypt and protect your data from unauthorized access. Windows 8 Pro also enables you to boot straight from a VHD which could come in handy.

Will everyone need these features? No, but enough will. It just makes sense to get the version that at least gives you the option if you need it rather than choosing the stripped down version lacking key features.

Oh, and if you already have Windows 7 Ultimate or Windows 7 Professional the decision has been made for you. The only upgrade path is to Windows 8 Pro.
