Most Linux distros are free, although not in the "professional" versions, which are totally complete. Some are excemptions such as SuSE which is unfortunately not free, the only free SuSE is the "live-evaluation" version which doesnt install itself to the HD, it only uses your RAM for you to test it. The only Linux distro besides SuSE that I am completely sure its not free (even the normal version) is Lindows:
www.lindows.com costs about $59, pretty expensive but compared to XP its hell cheap! And it offers the best eye-candy in the Linux World, comes after SuSE which is also awesome IMO. Most of the Linux distros can be found in linux.org which is an awesome site I must say, really great, I just love the "open source" community. Think about what a great person and how much effort this guy called Linus Torvald made and spend such a lot of time to create what today is called "Linux". Yes, he is the creator as are ol' Bill is for Windows. And Linus did IMO a great job since it took so much effort and besides effort the competition of the most used OS in the world called "Windows" (90 % uses it! amazing, what a lack of options IMO) But Linus wanted to change this and he started very well IMO, and im sure Linux is going to grow as much as it can, but first the Windows mentality needs to be quit. As for Macintosh, I just love this OS. I have always been a person called a "Mac Person". I always liked Mac. I used an Apple, dont remember which one, but definetely form the 80's to first 90's. This tiny little box that worked black and white, but I must say it worked flawlessly compared to the Windows OS in that time. It had a desktop, since Windows was more based in Bill's genuine invention called "Dos" that he sold to IBM and now he is one of the most rich people in the world. But I really dont know why Macintosh didnt and havent grow that much as Windows since its so great. I just cant believe that most people used Windows 1.0 when my Mac beated that OS really bad! lol. But now I just dont use Mac for two reasons:
- Its hell expensive!
-It has compability issues (not OS issues, but programs are more for Windows than Mac, and those for Mac are very expensive. Ex: MS Word.
Thats why most people tend to try out Linux since it works in a normal "Windows" machine (not like Macs that only works in a special computers just for them, that is why IMO they are the most less problems and issues OS in the market). Linux is great for those that want to take a rest and get out from the MS world or just to really get outta there!
Mates, I really made this simple (well, it was supposed to be) post a huge one! But, as you can see, I enjoy typing, lol!
Thats all mates, my opinions
