Solid State Drives - Finite writing capabilities?

[Trinatek]

I remember hearing some years ago that one limitation to solid state drives was that writing and deleting too repeatedly could become detrimental to the overall performance and/or storage of that drive.

How far have we come? Does this still hold any ground? Or is it a non-issue now, similar to the old worry of burn-ins with plasma tvs?

I'd like to be able to use Bit-Torrent on my MBA, but with the capacity of only 256GB I would find myself having to constantly free up space. No good? Or no worries?

You can write each cell of NAND memory about 3000-5000 times before it starts failing. For most people that isn't an issue since that's the equivalent of writing twice the capacity of their drive every day for 4 years (which most of us never come close to). However, constant Bit-torrent use would wear out the drive faster.
