Of course it's not a supported method, and no one really knows all the implications that may be caused by it. If it were me, I'd use the SSD if buying a drive wasn't an option (I use 60GB SSDs for OS drives in my personal servers).
The operating systems that are designed to run from a flash drive don't actually run from a flash drive. They load into RAM, and run in RAM, copying files back to the flash drive if they are changed (such as config files, for example). Windows is much to large to do this, and it's not designed to run like this.
