hello, very interesting article. there are however only two issues in the article. firstly where are those 40 viruses? I never knew that there are viruses in for the linux kernel or the gnu operating system. this is a misguiding fact. unix and thus linux can't have viruses. second. remember friends, windows xp will now sell for $3 for educational institutes and it wont be long before microsoft sells it at this rate for many reasons. windows is fast loosing ground at the desktop side as well and will do all things possible to hit the market again. so cost should not become a major point for promoting free software. although it is one important factor but there are other factores like virus and also the fact that due to the free nature buggs if any are often fixed fast and for the sake of fixing them not for earning market and money. regards, Krishnakant.
