I've been using Windows 8 regularly since last August and I haven't tried it on a touchscreen yet...other than demo machines in stores or other people's hardware, so I can't comment on the helpfulness of a touch interface. It seems logical that I'll probably get a touchscreen on my next laptop, but I've survived just fine without it so far. Actually I've found the Windows Key shortcuts to be the biggest time saver for me.
Touch looks like it might be a benefit, but it certainly isn't necessary to work with Windows 8.
