is there any reason for me to buy a new french press?

I've been using a bodum that's glass/plastic/steel I stole from a coworker almost 6 years ago. It's more or less been my daily driver ever since.

Is there any point to the specialty ones? Ceramic/doublewall glass/copper/etc?

I've been hesitant to change all these years because one, I got it for free, and two it's pretty easy to clean. But the metal mesh filter is starting to warp a little.
