As specified on Storm resources pages, Storm is not Universal Binary (i.e. it will not run on MacIntel machines), nor MS Vista compatible, and no update is scheduled at this time.
Just make sure Storm is compatible with your machine and/or OS; if it's not... well, just grab an old computer waiting for death on a dusty shelf, and refresh it as a Storm box.
Storm is low-resources consuming, compared to nowadays virtual studios, and is very convenient for 'old' computers (and probably notebooks).
