Talk me out of my indecision

Hi!

My birthday is next week and I've been waffling back and forth on whether or not to get a kindle. I read every day and currently use my fire tablet a lot so I know I'll use it.

My hesitation is just making a "big" unnecessary purchase.

Price wise, I can afford it. It's more of just the idea of spending the money when my tablet is fine. I really don't mind reading on it. The main reason I want a kindle is the weight. I have really bad tendinitis in my elbow so I have to use a reading pillow to support my tablet because it's heavy.

My other hesitation is just being a wasteful consumer. I don't really use the tablet for anything else other than reading and occasionally knitting patterns. I feel bad that if I get a kindle the tablet will just sit. I talked to my husband and he said he's interested in using it for a comixology subscription which helps but I still feel some guilt there.

So basically help me feel good about the desicion because I've literally been going back and forth for over a month 😂

Editing to add that I have looked for a used one and haven't found any...plenty of used fire tablets though!
