Power users may think they don't need touch, it's just a gimick for the unsavy consumer, if anyone is a "real" user, they won't even use a mouse - so why go touch. Well in the end, the "non-power user" is the majority and this is what companies will target in order to dominate the market.
It is the successes in selling to the masses that drives trends, not the hardy few power users. Innovation will follow inline with the majority and for the hardy few that decide they don't need touch will eventually have to upgrade in order to leverage innovations in software or even build solutions that have relevance in the market of today/tommorrow.
Personally I want to buy an ideal laptop that somehow has the touchscreen of an ipad, the performance of my workstation, the form factor/weight of a 17" ultraslim with a keyboard and the battery that lasts for at least 4 hours of hard use.
Is this possible, maybe not right now, but it is something that hardware gurus should be working towards and anything that gets close to this will secure a purchase from me and I'm sure many others - as long as the price is roughly right.
At the moment I need 4 devices to do what I do and I hate having so many: A high spec'd workstation for the days at the homebase, a high spec'd laptop for the days that I am not, an ultrabook for the time when I have to fly economy, and an ipad when I have nothing too serious to do. I think there is some definite room for consolidation here, but the tech isn't available last month, maybe sometime this year, we can only but hope.
