Pooky, I am still using my first generation Macbook (white).
I have been using it at work and at home for the last four and a quarter years.
The trackpad button has died, but otherwise the machine is still going strong. After 3.5 years, I swapped out the original HDD (which is still working) for a larger capacity drive, upgraded the RAM and installed the latest OS (Snow Leopard). I certainly hope to use it for at least 3 more years.
