I wish companies would follow the car company approach and fully separate their consumer-crap and quality corporate brands into to completely-different brand names. I tend to think that their consumer-end completely sabotages their high-end name. Everybody has a foul memory of a mid-range dell/hp/asus device and that feeds consumers into the "screw it, I'll just buy Apple" response. Make a brand that consumers can trust.
That's actually great idea I think. Would be not only more profitable for them, but also much better for me as a customer, as I wouldn't have to make detective adventure out of search for a computer. I wonder if they never thought of it or there're any problems that disallow them to do that.
