I'm kind of afraid to raise my hand - but I did.
We have an iPad 2 in our household that I bought for my girlfriend and she loves it. I have used it on occasion, but it has all her apps on it so I didn't want to put anything I like on it. At one time in the beginning I was toying with the idea of a Playbook but as RIM's future was in question, I opted out. The only other device I considered was the Nexus 7, but I wanted a full sized tablet.
I know it's a massive leap of faith on my part - but I like the idea of the ecosystem, and since I don't have any other Apple tech, it seemed silly to have a lone "orphan" iPad that won't integrate with my W8 laptop, my Windows Phone etc.
I guess we'll see.
From my standpoint, I don't see the RT being an "iPad killer", but as an alternate device - another choice for consumers.
