Backstory: A coworker overheard me talking about wanting one but not paying $400 for it. Turns out, his previous job gave him one for free. He wore it for a couple of months, didn't like it and put it in the drawer. He let me wear it for the weekend and I can buy it for $100. I liked it ok, even withdrew the money but when I woke up Monday morning, I felt like I didn't NEED the watch after all. My question is, should I buy it from him anyways? A decent Fitbit goes for $130. BUT, it's that time of year, I have to buy Xmas presents and what not, even though I have the money, I feel like I should be saving/using it more appropriately. Questions/comments? Am I an idiot for not buying it? Its still on my desk here at work.
