we are planning a Cassandra 1.2 installation at a client site; the client will run operations themselves and based on their IT team's experience they are more inclined towards running Cassandra nodes on Windows servers, however given proper arguments they would also consider using linux servers.

If you benchmark the two against each other, I would be shocked if the Windows version is not significantly slower.
The differences are often at quite a low level, like for example the mmap example, or the fact that Cassandra uses fadvise on Linux. Various optimizations only apply to the Linux version; even running Cassandra on Solaris would not make use of some of them. There are also supplementary tools (Priam, tablesnap) which may or may not work under Windows. It would be great if someone enumerated the in-code differences.. I have noted it for my extensive TODO list with the optimism of a new week... :)
On the other hand, if you don't mind taking the performance hit and being among a relatively small group of operators in Production on Windows, it should work fine?
