Never. I was too young for the SNES (which I still regard as best console of all time) and when I had the choice of getting a console at Christmas in 1998, I decided for a Playstation.
Obviously I couldn't afford another one at that time, so that was my only console at that time. As every German kid I had of course a PC which was at least capable of playing games that came with magazines... so that was my other option.
Then the next gen I decided to get an Xbox purely for Halo, which I played for hours already at my local store. Awesome decision. Though getting a PS2 would've also been a good idea, however I couldn't find many appealing games on the Gamecube. Especially after playing the disgrace that was Super Mario Sunshine. I rather upgraded my PC to a decent rig.
For current gen I only had a still rather powerful PC and my brother who bought a 360. I was extremely impressed with his games and bought a 360 a year later. Just in time for Halo 3.
Then a PS3 followed in 2009 when the £ hit its lowest point. Mostly because of the exclusive games I've missed out on, but even more important, I got it because of my love towards high definition movies.
Once more Nintendos console (Wii) didn't and still doesn't offer me that much games that I'm interested in. I've played the best ones though...on my PC *cough*.
Except for the Mario games, which are really good this gen, I was generally disappointed.
I have a Gameboy Colour though, which gave me lots of hours of joy.
