Having decided to get the PS3 as my HD console due to BR in addition to essentially the same games as 360 (exclusives aside) and playing Valve games and titles like Mass Effect on PC I just can't really justify the need for a 360. The actual number of titles I'd be interested in that I'd need one for are just too small now - Alan Wake, Gears 2 and Reach really being the only three.
At the time of purchase of my PS3 I was also a lot more interested in PS3 exclusives than 360.
I have a Wii but that's always felt like a totally separate thing, although post Move/Natal that might change.
It's not really cost though, as I could buy one if I wanted, I just feel there needs to be more need before spending money like that. I do play on friend's 360s though and if there was ever enough need for one to tip the scales I'd happily buy one, as I have no issues with MS or the console.
I didn't vote BTW as none of the options really seemed to match this position.
Try to be reasonable... its easier than you think...
