When in the generation do you buy your consoles?

[--OkeyDokey--]

i bought my wii at launch, which is the only time i have ever bought any console at launch.

i bought my ps2 a year after launch, and i bought my ds this year, soooo thats what 3 years after.

i did make the mistake of buying an xbox in 2006. yeahhhh, waste of money.
