Microsoft will soon be releasing its Windows Vista Os (formally Longhorn) on 1/30/07. the 2 coolest features are Windows SuperFetch and Windows ReadyBoost.
Windows SuperFetch preloads programs into your cache based on how often you use it or are likely to use it.
Windows ReadyBoost allows one to use flash memory or thumbdrives as ram so nolonger do you have to pop open your case and void your warranty to add memory to your pc, something like this is
great for individuals like me with 256mb of memory on my pc.
ready boost is also good because sometimes the ms os can be a resource hog taking away from rendering time.
i dont know if vista is going to be a 64 bit os yet or not (or if its going to be worth the upgrade) but it looks pretty good
