R u sure I doesn't have the camera?I m sorry if i had make u feel uncomfortable,but facts is facts,I don't blows trumplets, it is me. U r sure when u lift the glass there wouldn't have any problems at all. We just need to take out the lens and blow in our A 900 without any hindrance hence is up to individual and ways of handling. I still maintain my stand,unless there is great improvement,if not will not invest in any of the cameras at the present.
You said there is "No way to blow the dust away from sensor". As it is now on the A55, you remove the lens, then you can blow the dust on the pellicle away. Press the small latch and the pellicle flips out of the way, you can clean the sensor directly. Flip it down, done.
On the A900, you need to activate cleaning mode first as well, it's not as simple as just removing the lens and blowing.
Those are the facts, and facts are facts as you say.
