Duplicate content

Hi guys! Let's say I'm going to do a site about Sony Ericsson 610i. I made great review, put it on SonyEricsson610i.com and put 10 filler niche related articles I took from EZA, or simply have on my other sites. Will this affect my ranking on Sony Ericsson 610i keyword? Is this "bad" in the eyes of google? Could "SEOing" such a site be harder because of duplicate content?
