EggsAndSausage writes "Microsoft has granted, in a roundabout way, that Vista has 'high impact issues.' It has put out an email call for technical users to participate in testing Service Pack 1, due out later this year, which will address 'regressions from Windows Vista and Windows XP, security, deployment blockers and other high impact issues.' It's hard to know whether to be reassured that Service Pack 1 is coming in the second half of 2007, and thus that there is a timeframe for considering deployment of Vista within businesses, or to be alarmed that Microsoft is unleashing an OS on the world with 'high impact issues' still remaining." In other news, one blogger believes that Vista is the first Microsoft OS since Windows 3.1 to have regressed in usability from its predecessor (he kindly forgives and dismisses Windows ME). And there's a battle raging over the top 10 reasons to get Vista or not to get Vista.
