Jumping off a bridge analogy a bit harsh...
How about this. By volume sold, the best car is the Toyota Corolla (see http://www.automotoportal.com/article/Top_5_Worlds_Most_Successful_Cars_Ever).
Of course, MR AC Apple baiter is likely to own such a car. I think BMW, Mercedes and Audi make good cars but are not best sellers, so he won't be wanting one of those.
I'd contest that the best sellers are perhaps the most affordable or best value, not actually the best.
So, if you want the computing equivalent of a Toyota Corolla, get a HP, or if you want the equivalent of a Ford get a Dell. I'm not sure what an Apple would be - perhaps a BMW (you're paying a lot for the badge, but it is for the young, dynamic market and is made well.).
