Thanks for the suggestions!
Haha actually I'm more of a supporter of Panasonic than canon. Initially earlier this year I was thinking of getting 600D but due to no budget so I wait till now with a budget of 1300 to 1500, and with the introduction of G3 I was in a dilemma to choose between these 2 camera. Since both prices are so near. If I were to choose between these 2, m4/3 better or dslr better? Or actually both are almost the same?
M4/3 sensor is smaller as compared to Canon's APS-C sensor... thus it will not handle noise at high ISO as well as Canon's sensor. However after playing with my E-PL1 for sometime, I find that the noise control is pretty alright, right up to ISO 800, which is quite good already.
Like I said before, headed down the shops and play around with the two cameras. See which one you like best in term of;
1) Ergonomic (button placement, menu user interface, grip design, etc)
2) weigh (have a physical feel of the weigh)
3) Accessories available (external flash, dedicated lenses for different purposes, wireless transmitter, remote control, etc)
4) budget
5) size (smaller camera is easier to carry around, less bulky)
trust me... weigh can play quite a part here... especially when you are shooting for the entire day (I know... many times when I was lugging my 7D around for the entire day...I had wished that I have my E-PL1 with me instead).
(Edit: Did a short search in the internet and came up with this,

There is a short comparison of the G3 and 600D image... If you were to pixel peek, you will find that 600D's pic yield lesser noise and had captured more detail. But that is... if you are that particular on IQ. Basically... both had excellent image quality and both are pretty good.)
For me to choose though... if I didn't have my 7D and was new to the interchangeable lens system, if my choice of photography involve mostly brightly lit location (bright outdoors and very well lit indoor), I will definitely go with the G3... it give me the small size and weigh that I like so I can bring around whole day without feeling sore. If my choice would involve very low lit area, night shots, etc, I would go with a traditional DSLR... maybe 600D or 60D would be my choice... and if sports and actions is my choice of photography, I will forgo both G3 and 600D and go for either 60D, 7D or Sony's A77 (all of these have much faster frame rate).
So you see... it is up to you to choose and the type of photography you wanted to go into.
