They're struggling to compete both high and low. The iPad is pressuring them to put out a product that can use Amazon's VOD while BN is pressuring them to put out a device with a price that competes with the nook which has partnered with Netflix.
I doubt Netflix has any interest promoting either iTunes or Amazon services. It would be as stupid as Borders allowing Amazon to run their website. Hopefully this creates a nice trifecta of choice that benefits everyone.
On a side note; Borders was powered by Amazon from 2001 through 2008, until they decided to go separate and compete directly with Amazon. Of course this only mattered until Borders merged with B&N in 2010.
