Why a hybrid is like your smartphone camera...
A comment some people make about a hybrid tablet is "why would you want PC-like functionality in a tablet when it isn't as good as a laptop?"
I've now used the "smartphone camera" analogy a couple of times in the "real world" and it seems to work.
Think about this... a DSLR is big, bulky, an extra device to carry and inconvenient... but it's also the best device to take photos with.
Your smartphone camera isn't anywhere near as good at taking photos... but the convenience of "it's already with me in my pocket" makes it a valuable photography device.
Some people will use their DSLR all the time, others will get by with their smartphone, and still more will use a combination of both.
Well "PC functionality" is like photography in this analogy.
The PC side of a hybrid tablet can never be a powerful as a full sized laptop or desktop, just like a smartphone camera will never be as good as a DSLR, but the convenience of being able to access that functionality still makes it an incredibly useful tool, just like the camera in your smartphone.
Some people will use their laptop all the time, others will get by with their hybrid tablet, and still more will use a combination of both.
