The issue with putting your OS on the SSD has to do with your swap file. Windows (all versions - Win 7 is no different) will be pretty constantly reading and writing small files to your swap file. While SSDs are great at all forms of reading files, sequential, random, large, small, etc - they don't do well with random writes. Check out these links if you want some background.

I'd say the anandtech reviews are pretty much the defacto standard currently.

You see that some of these are much quicker than standard hard drives and some of them are much slower. Some are about the same. But with large amounts of sequential writes you can have performance issues. Not all SSDs (very few of them initially) are designed for the type of use that you would expect to use for your OS drive.
