It is futile to try to get more disk space. Data expands to fill any void. If a program actually fits in memory and has enough disk space, it is guaranteed to crash. If such a program has not crashed yet, it is waiting for a critical moment before it crashes. No matter how good of a deal you get on computer components, the price will always drop immediately after the purchase.
All components become obsolete.
The speed with which components become obsolete is directly proportional to the price of the component. Software bugs are impossible to detect by anybody except the end user.
