Conjoint Analysis - An analytic framework for deciding trade-offs between features

I did this a while back while scoping out trades offs between price versus hardware inside a tablet. Hardware features looked at are often focused on "CPU" and screen size. 

Application Processor (AP) is the CPU brains inside of a tablet. Why called application processor? Because the AP often not contains a traditional CPU, but it often also includes a separate graphics processing unit (GPU) - needed to make streaming video more smooth and makes games more realistic. There are two major AP architectures : ARM and Intel. ARM has been licensed by most AP design companies : Apple, Qualcomm (which then is sold to Samsung, Apple, ...), Samsung, Mediatek (then sold to HTC, ...), etc. Intel's Atom has been used in less brand known tablets such as Acer.  Indirectly tied to the AP is the size of the local memory (DDR). 

Screen size is the other dominate hardware feature used to make a tablet purchase decision. Some consumers look at the absolute size (diagonal measure, pixel count) as opposed to pixel density (how share the display will be). 

Here is an quick of a conjoint analysis.

S(N) denotes screen size. P(N) denotes # of processor cores and RAM. The conjoint (crossing of the S(N)xP(N)) denotes segments - and targets personas/use cases/budget.
