I grew up extremely poor to the point where I had to use the bathroom in either a bucket or a hole outside. Moved after I turned 19 through a program for youth and have an apartment, savings, and I'm going to school for a career in healthcare. It felt weird buying a laptop for classes now that the Pandemic pretty much changed everything. Just bought myself new clothes too since I've had the ones I have now since my late teens with the exception of my shoes.
That is normal to feel weird or cautious in Buying Laptop since this is expensive and you are thinking about the Amount you are goind to spend is Bigger compared to how much you wanted to buy this.
But remember that you need one for school so either Buy brand new or buy Second and that is in good condition .
but for me practicality ? i am for slightly use gadgets as i know how to check them and assess their condition on the spot.
