I changed the main article from Machine to Machine (mechanical) because the current version of the article Machine emphasizes computers and not the mechanical devices listed either as subcategories or as pages in this category. If this is controversial, then I apologize, and will change it back. Prof McCarthy (talk) 09:18, 12 October 2011 (UTC)[reply]
