I checked that out before I bought. As far as I could tell, it's not really an issue with any half-decent SSD, since they automatically level below the file system (so even though swap is a small part of your disk, it doesn't mean you're putting all that load on a small part of the memory) and also the numbers seem to work out like you'd still get many years of use.

Anyway, for me, I suspect it means I'll keep this laptop for an extra two years. It was starting to feel sluggish if I had, say, firefox and eclipse open. Now it's like new. Would really recommend it... (but it is true I am on Linux...)
