I went ahead and added the leather storage pockets to my 2014 M3W order today. Based upon the comments here, they don't seem useful, but if my phone will fit, then I figured it would be worth paying for the option to make life a bit easier. The netting with clips is a fantastic idea too, though, so I'll also be adding that later as a way to carry larger items. Thank you for linking to the original post.
I also ordered the heated seats, but did not get the immobiliser or intercom.
