I've had a 360 since launch and, despite its non-appearance in this poll, a Wii since launch also.
My 360 gets used pretty much every time I'm at home, I worked my way through all the Wii games from launch very quickly and it got an intensive bout of use shortly after Christmas, but since I've finished Zelda it's not been touched... Waiting for Mario Galaxy and a few others now.
I wavered a lot on PS3, I just couldn't see the point initially, I was happy with the 360 and there weren't any real exclusives for the PS3 I was desperately interested in, so there was just no need for me. Then I felt like I should get one just to be "console complete" and as I have the HD-DVD drive for 360 it would give me both movie formats...
Ultimately I decided to wait and see one, given where I work that was always going to be easy enough. We got one in here at launch and I can't say I was impressed, I took it home for the weekend to see it on a better setup, but (in my opinion) the interface is terrible compared to 360 and there just wasn't a launch game which held the attention of myself or my brother for more than an hour or so.
So for now I'll be sticking with just the 360 and the Wii, with the 360 my primary console. I'll revisit the PS3 concept if any games come out that I absolutely must have and can't get on 360, or if everything starts heading Bluray in terms of films, but until then it's the much discussed Wii60 combination for me.
(used to type this message, by the way - if my posts become more to the point, you can also blame Sony's typing interface programmers, as they limit the maximum form input right now ...
