Yeah, I get it that not everyone will be able to use this. However you and I will and a lot of others will, and better screens are getting cheaper all the time so the numbers will increase. As it's optional, no-one will be forced to adopt it, if it doesn't work for them. It's good for those with nice screens now, it will be good for most people soon, and its an easy feature to implement that nicely sets HTC up for the future. win/win/win, what's not to like?
