I was a devout N=1 guy. Then I made a similar mistake, and test rode something that was the polar opposite of what I ride every day. I put 20K miles on a KHS CX300, then another 5K on my Ritchey Swiss Cross before ever sitting on a proper road bike... and it's a whole different thing. I honestly don't think I could live life as an N=1 if that ONE was my Cervelo R3. But it is a fantastic thing. It's just fast, all the time.
So be thankful you just looked at them and didn't ride any of them. I had no intentions of N+1, and that R3 came home with me. But I'm quite content at N=2, because even while doing the same sorts of things, the Ritchey and the Cervelo are as different as two diamond frame bikes could be, as far as I'm concerned.
