Vista starter will be like your old Dos 6.22 bootup disk. Bootup, command screen and everything else you need to get extra.
Nobody needs Vista at this moment - nor there is any reason whatsoever to get it. Only fools who are willing to do betatesting and pay for it will install it for the next 2 years or so.
If we're lucky, hardware will develop so much in two years that we can get a computer that will perform the same as yours does now in XP for the same money using Vista.
Anyone tried installing Windows95 to a current hardware? It flies like it's on crack. Too bad they've stoped driver support.
