I wonder what will happen with the UI for the release. I can imagine that if done properly it could work (Modern UI that is) but the way it was implemented in the consumer preview was pretty botched Thankfully there are third party replacements for the startbar. The PC Win 8 UI just doesn't appear to have had much thought put into it, and it understandably was not Microsoft's main priority, playing catch up with Apple/Google on the tablets probably is.
For desktop computing I don't really want people touching the monitor, it leaves fingerprints. Maybe some future version which can read hand gestures might solve this but for personal desktop computing it's a bit of a marginal feature IMO, but might mature into something better in the future.
Form people that have used Win 8 consumer preview for audio they seem to need a larger buffer size for streaming that they did in Win 7, so I'm not sure if I might need a more powerful CPU or ram or what. Intel is also on my grudge list for changing the pins on the CPU every 2 years for no obvious reason apart from "product life cycle" greed.
