so, as a user, should i try it? will it be time-consuming(the whole process of installing and getting to use it!)? i am asking abt this OS as i have the DVD of it! also, one DVD is for SPARC system and other for x64/x86 system! which one do i use?
You need to use x86 DVD. Install VMware or Virtual PC to test it out. That ways you wont have to deal with HDD formatting etc and installation of Solaris can work in parallel with games / browsing. It is useful only if you plan to get into software development / IT Infrastructure. Solaris is a much better platform to learn advanced C/C++ as compared to linux. Mainly because GCC that is available by default in Linux is very bad in generating debug info.
