Carl Zeiss maybe a good lens, and Sony may make mass market camera's, but you will NEVER see a professional photographer with Sony gear.
Canon/Nikon make the best camera's hands down, followed byKonica Minolta/Fuji/Pentax, but sure if your in Dixons you can pick yourself up a Sony.
And stop welling on a single point of my comment, .RAW photo's as i said may not be utilised by the majority of folk wanting a point and click, but given choice I personally would use .RAW on static scenery over another compression. Yes you wouldn't use it for trackdays, but thats a different type of photography all together.
