Example
Dear friend,
I’ve had a pretty frustrating time with my new Dell computer lately. At first, I thought it was a good purchase but then I realized that it was kinda slow.
I installed Ubuntu in it and still felt slow.
Then I realized that the problem was the RAM and State Solid Drive (SSD)
I had to spend like 40 thousand colones on a new RAM and a new Hard Drive
So you better do you homework before buying a computer.
Can’t wait to hear from you.
Sincerely,
Jose
