16Gb for £100 - is it worth it? I'm going to go out in a couple of hours and get a Nexus 9.   

Argos has the 16gb model for £200, and the 32gb model for £100.  Is it worth paying the extra £100?  It seems to me that the price point for the 16Gb one is very very good, but the 32gb doesn't seem anywhere near the value.   

Any thoughts?
