As long as you're buying because you like the cel 
and know it will bring you countless hours of 
pleasure and most importantly, if you can afford 
it, then why not. What's the difference between 
spending $2K on a big screen TV and a cel? It's 
whatever that gives the most value to you 
personally. Besides, cels are one-of-a-kind. Big 
screen TVs will always be around and the longer 
you wait, the cheaper they get and there's always 
new models on the horizon.

Of course, if you invest that $2K in a Roth IRA, 
at an average of 8% compounded for about 30 yrs, 
that's quite a bit of change. You didn't want to 
hear that, did you :)?
