And\n 13 percent of respondents have already completed a migration to\n Vista, compared with 6 percent in February.Improved security and performance top the list of Vista's\n most-attractive features, with 65 percent of respondents citing\n security and 55 percent citing performance as the top benefits\n they believe they'll see from implementing Vista.As for concerns surrounding Vista, expected bugs tops the\n list. Fifty-one percent of respondents gave this as a priority\n consideration when thinking about implementation. That number is slightly less than in February's poll, when 52 percent cited that worry. Respondents did show less concern about Vista's hardware\n requirements, compared with February's survey. Twenty-seven\n percent now say that hardware requirements are excessive, down\n from 37 percent.Despite the upward adoption trend, a significant number of\n IT shops still view an upgrade to Vista unnecessary.\n Thirty-seven percent say that their current OS meets their\n needs; that figure was 40 percent in the February poll.
