Difference between Liunx and Windows

We all have gone through this discussion somewhere in our life and we keep doing this. I respect both software in sense they have there own commerical market. I did not rate any one above other as they target different audience to me. Its just that they try to take others market in different fields. Some one told me Linux is free, Okay its free so...I have to download 700MB CD to make it run and Need a Internet connection to download all its free softwares and have to be connected to internet all time to make it run whenever I got any error. But on windows once paid I never have to call there customer support nor I did need to Search internet for solution.. it just run every for me... For me its Cost is Covered..:D Okay thats not my topic of the day. Let me give my points Linux * Has Better Security than Windows because it has Better User Rights Management (User Management is similar in both) its just that Linux has use better Rights policies from scratch. * Has Speed and Control of even the smallest application like even you can remove Copy file command from your linux box. Windows * Has Organize Developement Framework : Please don't argue this with me, if its not than my PHP has two different version running parallely to each other , Why I still see Kernel 2.4 source for download , Why we have issue with upgrades on linux more than Windows. the truth is that Windows use Oops in better way than Linux, Most of Open source software are in process of having two version running simultenously, but Windows run one software at a time (technically) not in terms of version . I dont mind having Red Hat linux and Debian Linux and Fedore. * Has Better User Interface: yes there are themes in linux much better than Windows (not Includes Vista here) But I really feel these theme loose consistency and User has to see and wait for mouse over popup to come before he click on new theme button. Now with Vista Windows lose that point I guess though I never review it. (Anyone please send me its CD .:oD ) * (-) Bulking Graphics Engine and Too many Bulk code is going with windows, I believe Microsoft never clear their Code for Windows if they does Its install size must reduce by 200 -300 MB they have lot of Useless bulking code and software going with windows... Hope I didn't break some ones heart Sumit Gupta
