I love ubuntu but here in our community windows is most used platform, so I've to use windows as well.
Hmm... Although, i'm a Ubuntu user ( & lover ) The new Win7 makes me think... Yeah, it's great and all, but i dunno... I have a Win bug or something... I like working on it, but i can't shake the feeling that every info i put on the Pc is unsecure. And Ubuntu gives me freedom! I don't have to worry about that. And I can do everything ( or almost everything ) on Ubuntu that I can do in Win7. So, Yeah, Still Ubuntu
I have never use Ubuntu, i have always find that windows is more user friendly xD So i prefer windows xD
In some cases there is no alternative of windows OS but Linux is the best for security. Ubuntu is little hard to use for new user. If you use to with this OS you will be advanced user for all respect. We can use Linux for common use place where we need only browning such as data entry company, cyber cafe etc.
I use Windows and Linux at the same time. Of course, my main job based on Linux platform while using Windows in simulating server environment.
Both of these operating systems are exceptionally great. Right now I am using Windows. I believe this is the most widely installed operating system since 2001.
