When I read this one-line ad in today's PC World email news blast...
Earth Day Sales
Save up to $640 on select [Lenovo] Thinkpad Laptops through April 27
...I knew that commercial interests have corrupted yet another day meant for altruistic reasons. Earth Day in on the heap, along with Christmas (most important buying time of the year), Easter (chocolate rabbits), and the other holy-days.
The connection between Lenovo and Earth Day? None, except an excuse to hide poor sales behind an unrelated event.
