With SLIC 2.0, you will only be able to activate Windows Vista but will not be able to activate Windows 7 when it comes available.. With SLIC v2.1, you will be able to activate Windows Vista and Windows 7 However there is no ASUS SLIC v2.1 at this time....so, it is up to you and I am about to head out to get something to eat... The DELL SLIC v2.1 gives you a lot more options.
. . . very thoughtful of you to give the options as you see them; but an ASUS 2.0 SLIC will work fine for installing Vista - I have an Asus DVD - into this little box. . . hope the eats is good . . .
