Here we are again. He asks advice and when he is rebuffed he disagrees with the helpful suggestions everyone has offered. Is a computer a necessity? For me it is; it allows me to work at home and check on the work I supervise without being at the office 16 hours a day and allows me to work from the road. But I paid $320 for a refurbished Dell Windows 10 laptop that does everything I need (truth be told, I wouldn't have bought it, but a burglar took the previous laptop).
It connects with my Windows phone ($60), so I can use the computer about anywhere. The thought of paying hundreds of dollars for an Apple phone is nonsense.
Same with DSL. I use it for work and entertainment. Same with my cellphone. I have to be available 24/7. Not optional with my job. It may be with yours.
I admit I have a TV, which I bought when the one handed down to me finally gave out.I could have kept watching the 15-year-old tube set, but I admit I couldn't go back to CRT. Bought it on sale.
I canceled cable and picked up Netflix and Hulu and put up an antenna. Saved a lot of money and still can watch TV (can't say I've missed anything important). I watch mostly PBS, which is free.
All of this is to say that you can spend a little bit of money to meet your needs and wants.
I will admit I have a weakness for camera equipment. I bought a new camera because I can use it for both work and recreation (and partly because the burglar also took my camera). Almost everything I buy is either used or refurbished.
I'm cheap, and as I grow older I get even cheaper. I find I need (not want) to save money for retirement and to help my children. I buy clothes at Goodwill and the Salvation Army, even though I can afford "better."
I sympathize because I've been at a time when it was paycheck to paycheck hoping all the bills would be paid. We all want nice things. But often something not quite so nice will accomplish everything we really need, and even want.
