Your Honda versus Acura muddies the comparison. Acura is a luxury brand. The consumer gets clear value-add through additional comfort, improved build quality, better customer service, etc. The differentiation is clear. The target customers are also different. In the Google/AWS example, additional power/capacity can either be incremental (10% more RAM, etc), or class defining (web server versus super computer). There may be other attributes that stand apart, but everybody seems focused on price and cpu/ram. I don't know AWS well enough to honestly compare, but is Google's service incrementally different, or does it provide a capability that AWS doesn't offer?
