Pentium 3 Laptop
This laptop is around 11 years old.
Most people would have thrown it away long ago, but this is actually my primary laptop for school and work. It boots up faster, shuts down faster, loads programs faster, and is generally more responsive than many computers purchased today.
When people complain about "slow" computers, the problem is almost always software-related, and has nothing to do with the hardware. Yet, most people feel they need a new computer.
