I want to buy a new computer
Why do you want a new computer?
I have many reasons why. Two are that it is both more efficient, and I am a huge fan of blue colors.
It's expected to want the latest tech available. I want a new computer also but I can't afford atm.
It is fine, I think my life will be much better having a new computer.
Wanting to have new tech is completely fine as long as it is within your budget. Somebody require to have up to date tech so they can do their jobs, especially being as how so many jobs are remote now. Just do your best to shop around so you know you are getting a good deal.
