Yes, very true and can be fixed by software updates and its most likely coming, but i don't think HTC can give a software update to move the sensor in the front !!

Apple was not the first one, Apple doesn't have the market share, Apple is closed, Apple is overpriced low spec'd, Apple is doomed,
YET, it seems it's only after

iphone 5S the world got introduced the fingerprint sensor. And, even after that too, people are still struggling to copy.
Samsung has better photocopier in their lab than HTC, we should soon see some very great innovation from Samsung, something like never seen before fingerprint sensor!!, that unlocks the phone just by pressing front home button !!
