I don't think it is worth it. Only 45mb read, write is prob a bit less. The cost per gb is crazy (for now).
Flash write speed is really bad compared to it's read performance.
For "ordinary" flash memory, it will start to deteriorate once the write count reached few hundredth thousands write activities on every cell (bit), remember each byte consist of 8 bits. It has a finite number of erase-write cycles :)
So even it is cheap and let say as fast as harddsik, if you use it just like ordinary harddisk like OS, pagefile and etc, it will failed within months cause by those many-many write activities.

That's why I put the word "ordinary" in quotes. :D
