TL;DR: Please use Adapters whenever you need to show lists of data:
http://docs.xamarin.com/guides/android/user_interface/working_with_listviews_and_adapters
Adapters reduce GREF counts by ensuring that you only have GREFs for _visible_
items, not for _every_ item in a list.

How many elements are in `productlist`?

Should probably throw a GC.Collect() in here ;-)

This is where things get horribly wrong with GREF counts. We have a GREF for
the view.

A GREF for each of these TextViews.

This button.
So for _each_ ProductDetail, you have 6 GREFs. If you have ~333 ProductDetails,
you can't run on the emulator.
