@riyaz :
I tried netinstall using dataone for my uncle who wants debian for his lateX works,,,it is eqiuvalent to cd install except downloading packages according to your setup.in the process installer will ask you to setup your internet connection.beware of the ncurses installer while selecting preset install options.for eg; Installer showing which preselected package collection to install .the options given are like Desktop env,server install,.. etc..there is already graphical(Desktop) environment appeared to be marked.but it isn't.
u need to select needed by using '_' space bar;thus there will be two aestrich(*) marked.a Desktop install needs some 500~=MB download (not sure)
If U r expert U can select packages manually by aptitude...
