I am an example of a noobie who has upgraded from a C camp Point and Shoot to Alpha 300. I was bought over by the live view capability of the camera. I discovered that the shortcoming of the Alpha from day 1 especially when I need to take a photo indoor without flash. I tried taking similar photos on my friend's 500D and D60, and I immediately noticed the advantage of these 2 models. Less grainy indoor picture. Although the colour of Alpha is much livelier. I guess a person should expect this capability even from an entry level DSLR. Otherwise , he may be better off buying a SLR like camera, cheaper and smaller and easier to use...... I am unsure if Sony can maintain the Liveview advantage from the rest for long, before the big boys catch up and the story of Minolta repeat once more.....
Just my 2 cents worth.....
