Sherwin-Williams [1], the NEO based paint company is also known throughtout the Open Source community as one of the first major companies in the U.S. to rollout Linux for their retail infrastructure. IBM [2] has them listed on their site with one page description of what they have done. Needless to say, IBM was the system integrator and hardware supplier for the deployment of the system.
Sherwin-Williams is, as most of you already know, a 25,000 employee company with a retail operation of 2500 stores throughout the United States, Canada, and Puerto Rico, and 52 manufacturing plants worldwide. The IBM marketing blurb [3], the system includes 9700 Netvista boxen running Linux in all 2500 retail stores. The POS system will also run linux apparently.
This is a fairly old story in fact. I remember it from a few years ago while I was still in Japan. However, since I didn't know whether folks here at RealNEO were aware of it or not, I thought I would post it. If it is a repeat, my apologies.
