when i bought my first Android device i didnt root it for 9 months. I thought the same like you then one day i root it now i cannot have a device without root.
when i bought my Samsung Nexus10 and nexus 4 I rooted it the very first day.
but before you even root you need to know why you want to root? first step is to check if you have come across any app which needed root to function?
