iPad Mini or Kindle Paperwhite + Nexus 7

So the question is- I've got $330. Do I use it for an iPad mini or for a Kindle Paperwhite and a Nexus 7.

I've managed to resist buying a tablet so far, but it's finally feeling like they are mature products.

My ecosystem is very mixed. I use a Verizon Galaxy Nexus (but haven't bought much from the Play Store), Macbook Pro for work running Windows 7 in Bootcamp (main apps for work are windows only), Custom built Win7 PC at home. Fiancee uses a 13" macbook and iPhone.

I plan on using the tablet for reading in bed or on the couch, and for consuming media while traveling. Nexus 7 kind of just looks like a bigger version of my phone, without much more utility. Kindle sounds great for reading in an airplane / on the beach, but seems like a limited device. I feel drawn to the iPad mini's size and great app selection, but I kind of despise iTunes and DRM. I could use the Kindle app on the iPad for my reading, and feel comfortable knowing that I'll have every app I'd ever want on iOS.

Any advice? My fiancee keeps asking what I want for Christmas and I can't decide! Surface looks interesting, especially for multitasking, but it still seems half baked. I feel like it's best to wait and see what the Surface Pro or Surface 2 has to offer before jumping on a new bandwagon (this coming from a burned WebOS fan).
