Microsoft will be able to delete files through a special code in things you download like if you buy a lisence for music that lasts for one week etc...
then, just dont buy it! Noone says you must buy Longhorn (when its there in 2007)
and dont worry, everything has a crack.
I'm no computer fool but I could not for the life of me even download and get to run the simplest of programs off their site.
If thats the best Linux can do they can stick it.
Being free is'nt good enough.
get a copy of Redhat or SuSE.
Try SuSE Linux 9.2
