Should i get an iMac?

My mom's Fujitsu laptop is breaking apart, the CD drive no longer works. So I want to buy her a new computer. She is not going to do any gaming or anything, just some Korean-drama watching and Microsoft office programs. And maybe listen to some music. I want to get her an iMac 21.5 Inch, but is the iMac really good enough for basic home usage? because i am a gamer, so i have no idea what a regular computer's specs would be. If the iMac is not good, then what computer would be?
