For Windows desktops (not Windows Server editions), the swap file should never come into play. Any machine that is swapping needs more physical memory. With laptops capable of taking 8 or 16B and with 4GB sticks being cheap there's no reason not to put 8 or 16GB in.
The better wear leveling algorithms actually move the physical locations of the underlying blocks. While the OS is writing to block X, the reality on the disk is writing in different spots. Pretty effective technique too.
I've been on my current SSD for about 18 months, I'll let you know if it fails soon. It's on a MacBook Pro, so I don't expect it to be problematic.
