Exactly not so much is there abt to talk abt Longhorn .... let it be exposed first ...... & wat all we have is alpha versions which doesn't show even wat will be the product when it will be released tht;s y it's of no worth to talk abt longhorn right now..
AS if alpha version is concerned i think Microsoft r trying to give windows an eye pleasant look ... it's great thinking by the businessmen & techies...
