linkRoot will bring u new options - just to make it simple to understand - u can
1. remove apps that u dont like or dont use - improve battery life and speed + u can add anything available!
2. costumize icon + status bar + dialer and much more - make your device on "your style"
3. flash any working avaible ROM with diferent features - what u like u will get
check out for example
1. cognition - simple fast and easy to use
2. MIUI almost unlimited options for changing themes and much more
3. caynogen - stock android - clean and clear - fast and stable
and like this you will have lots of options - i took out few that i like most but they are many more out there.
rooting is the option novadays - dont worry everyone was rooting first time! dont be afraid - believe me.
