June thats what I meant the end of June. and no, supplies won't dissappear... had a big boring discussion and look over this in comp sci class yesterday
January is when actual copies of the OS won't be available anymore, and updates other than security related ones will cease to be released in mid 2009.
Total support and updates for the OS don't end til January 2014... hopefully by then there will be an OS i can buy and skip right over vista, God willing
