I've never had a problem with Visat, and have over 5.5Million files running on it, and God knows how much hardware.
W7 will have security issues, and Vista "plug in a device,camera,flah drive etc in seconds its installed no need for instalation disc in most cases" does this!
It is a memory hog though needing at least 2GB, but that is not the software, it was the way they done the memory management which thinks it knows what you may use next and pre-loads it into memory, except in my case it gets it wrong 100% of the time as I use so much software.
