Root or not to Root???

It depends wether you neet root access or not. If the apps that you wanted does not require root then dont root. As rooting your phone will void you warranty, unless you unroot it which is very hard although possible.

Even I have rooted my samsung galaxy ace mainly because i want to use that overclock feature to improve my phone's performance during heavy gaming . Also rooting provides me with the ability to install custom roms like the cyanogen mod which gives me the ics version of android even though its not officially released for my phone . Also there is an application called lbe privacy guard which intimates you when some other app which is tying to access your messages and internet without your knowledge . So I personally feel that is cool mainly because i used it install new Rom of ics . So i personally feel that rooting is actually a pretty good thing to do with your phone .
