Online trading or Mutual Funds?

To follow up on my last post, a friend told me that ICICIdirect has good online trading service. But now I am in a dilemma. Would it be worthwhile for me to jump into online day trading? Mutual Funds (MFs) seem much safer in the expert hands of fund managers even though they have some fee associated with them. I've read somewhere that MFs have to pay less tax than traders and so in the long run MFs could yield better return. Need to chose MFs which are diversified.
Guess I will wait for a while to learn more about the pros and cons of Online trading vis a vis MFs.
