I have spoken to several professional photogs, who all share the thought to buy a camera from a company that primarily makes cameras. I LOVE Sony stuff, but can they really be experts in radios, TVs, Plasma TVs, car stereos, MP3 players, cameras? Not so much.
I share my peeps view here that Canon is an amazing product, built to last, easy to use, etc.
Stay away from HP, etc. companies that don't have an extensive history in cameras.
Best of luck
