Excellent post. Too often, product guys and business guys don't really understand each other or the value that each bring to the table. I've lost count of the number of times that I've watched business entrepreneurs try and hire a code monkey to build their vision for a tiny fraction of the equity, knowing that they'll probably fail because they place too little emphasis on the product and technical vision, especially in the early days. Similarly, I've seen a lot of disdain for business entrepreneurs from the hacker side of the tech community, probably partly due to backlash from the "code monkey" mentality described above, but also due to a fundamental misunderstanding of the value of marketing and sales. Both sides are important, but which is more relevant is determined by the phase you're in.
