Hi i have the same samsung X20 laptop..
have upgraded the hard drive and ram alone..
i tried installing windows 7 on the machine..
installation went fine..
all the
drivers were perfect except for the display/graphics
driver..
i was not able to get the transparency effect on it..
is it possible to get that and aero working by the compatiblity installation of the same??
i'll be real glad if u give me a work around to upgrade from XP to 7
because im trying to network it with my new win 7 machine and i am unable to from XP...
thanx in advance..
